  1. Happy Butt Yahaira Shapewear

    Posted by Chely on Sep 27th 2019

    I recently purchased the Yahaira shapewear and I really like it. It fits true to size. Very comfortable and it really shapes your body to make you look amazing! I will warn you, it is a challenge to put it on. It took me 25 minutes to put it on the first couple of times. The product comes with pictures which show you how to out it on. The only downside I saw was the bra attachments were very difficult to fasten and the lining at the top is very uncomfortable.

  2. The best body shaper ever

    Posted by Lisa on Sep 27th 2019

    This is the best body shaper I’ve tried and I had my share of them it fits so comfortable and it really helps my clothes fit better !!

  3. Best shapewear period

    Posted by Giawilson95@gmail.com on Sep 26th 2019

    My confidence has boosted with this shapewear. As someone who doesn’t want to go under a knife to lose weight, through the process of losing weight this has helped a lot.

  4. Wow!!

    Posted by Carletta on Sep 25th 2019

    I've been wanting to buy this for quite sometime but the price $$$ held me off. Then I finally told my husband... You're purchasing this for me!! It arrived quickly and when I took it out of the package he says, are you sure cause it looks to fit a child?

  5. My butt is definitely happy!

    Posted by Unknown on Sep 25th 2019

    I LOVE that this shapewear doesn’t flatten my asset! I’m Latina and appreciate this very much.

  6. Worth the $

    Posted by Kim on Sep 25th 2019

    I'm 5' 2" and 150 lbs. I'm larger in my waist and hips, pant size 7/8. I ordered a nude, size M and it fit perfectly. It wasn't hard to put on and the quality is very nice (I wore it under a thin, stretchy black dress and it didn't show).
    The straps are adjustable and completely detachable in case you don't want to use them. It stays on well, even without the straps applied and it was very comfortable to me, it didn't roll down at all. Adjust around your hips well and your booty will pop! ;)

  7. Love it

    Posted by Unknown on Sep 20th 2019

    I love this body shaper and with straps to adjust to your bra it never folds down! Thank you Yahaira!

  8. Best shapewear

    Posted by Jazz LG on Sep 19th 2019

    So I've tried several shapewear and has been a waste of money, this one is kinda difficult to put on, maybe because It's still new but once is on omg it's so comfortable. I love the straps since I use to always end up with my face all rolled out. Yesterday I used it with jeans and tank top and there's no way it's visible and I also used it with leggings and you can't notice it at all.

  9. La mejor opción de mi vida

    Posted by Lilly on Sep 18th 2019

    Tengo realizado mi Lipo y bbl al final de mi recuperación, tome la opción de comprar la faja de yahaira no. 7que mire en internet, Para tener una mayor comodidad, quede enamorada de la faja, sobre paso mis estándares, soporte, comodidad al realizar ejercicio y al trabajar, sobre pasa las 5 estrellas yo daría 2 mil ⭐️⭐️⭐️⭐️...
    Solo si me hubiera encantado que estuviera la faja no. 7 con cierre el tommy T.

  10. Amazing

    Posted by Mary on Sep 18th 2019

    When I 1st saw it I got scared it was literally the size of my 2 year old nephew and didn't know how I was gonna put it on. When I got it on I was amazed it's so comfortable and my ass looked amazing!!!!!


    Posted by Monica on Sep 16th 2019

    I was going to return it thinking I got the wrong size but it fit perfect. I got a large and I'm 190lb size 12 pants size. First time wearing it will make you think it's too small but it expands more as you use it the 2nd time. I wear it everyday and hand wash daily. I hang it up to dry and it dries fast. I love that it so comfortable and yes I can see the difference! Definitely will recommend and looking to purchase more. One thing that may need improvement is the strap in back and on sides, it's difficult to put those on by yourself.

  12. Best ever!

    Posted by Unknown on Sep 16th 2019

    You could wear it all day you will never get tired of it!

  13. Amazing!!!!

    Posted by SarahB on Sep 16th 2019

    This product is my favorite!!! Shipping was fast and product is very high quality. I HIGHLY recommend this product to anyone. It really does exactly what it advertises it does. I will definitely be ordering more in the future

  14. Awesome body shaper but...

    Posted by Kyesha on Sep 15th 2019

    It don’t hold my stomach down as much as I’d want it to , I should of just brought a smaller size.

  15. Una faja que no te tortura!

    Posted by Alba Gallardo on Sep 13th 2019

    Una de las mejores fajas que he comprado, me ajusta adecuadamente sin quitarme el aliento, flexible y lo mejor no se notan las costuras!

  16. Needs Improvments

    Posted by Maria B. on Sep 13th 2019

    Happy butt was good I liked it a lot but one of the straps fell off and now I have 3 instead of 4 . It would of been helpful if it came with a few extra straps and it’s kind of hard to fasten the strap in the back to your bra but it’s managable . I do like it and still use it because I paid a lot for it but I am looking into getting the full body one that goes over your shoulders because the straps are just not good .

  17. Love it

    Posted by Lisa Lola on Sep 12th 2019

    Worth every penny I have told
    My friends u need this

  18. Feeling confident

    Posted by Jessica Anderson on Sep 11th 2019

    My clothes fit so much better!!! Now I feel more comfortable and confident. Definitely will be purchasing more products.

  19. Great product

    Posted by Latresia on Sep 11th 2019

    I love my garment!! I was very skeptical when I ordered but when I received it and put it on I became a believer baby. The only thing I had a problem with is getting into it lol I had to strictly follow the directions and have a lot of patience but once I got in it it was COMFORTABLE, which I feared but this shaper is the bomb! I highly recommend it Ladies my money was well spent and definitely ordering again because I ordered a xl and yahaira told me to get a large. I should’ve listened but I wanted to be on the safe side. Completely undetectable, and enhances your curves. I love love love this shaper!! ❤️❤️

  20. 1

    Posted by Tiff on Sep 11th 2019

    I like the comfortable feel of the material. I do think the stay put type silicon around the Leg should've been completely around the with to prevent the slight rolling up. The buttocks area should have more room for wider, bigger or rounder behinds. I wear a sz 18-20 and the XL is a good fit. I can't wait to see the results of it helping to reduce cellulite without wearing it. This Product does smooth out your shape and skin while wearing it. The stomach area just smooths you out nicely but doesn't flatten the area. Lastly the bra straps were a good idea to have or choose to remove them. This is the best by far shapewear I've tried as of yet but the priciest as well. I would like to see the company make an XXL.

  21. Very satisfied

    Posted by Maria on Sep 9th 2019

    So far one of the greatest I have had.

  22. I’m in love

    Posted by Lisa Lisboa on Sep 7th 2019

    I have been eyeing this shaper for ever ! not wanting drop $ but girl this is worth it for sure , it’s a bitch to get on but the instructions were very helpful. but dam my waist is snatched and wow it’s so comfortable so I want all the pieces now!!! Best body shaper . I can’t wait too see what coming out in October.

  23. Enamorada

    Posted by Raquel Guevara on Sep 6th 2019

    Me levanta perfecto las pompas que claramente son las tuyas y no relleno, súper cómoda y puedes ponértela con lo que tuvquieras

  24. Amazing shape garment

    Posted by Minerva Ramirez on Sep 6th 2019

    I love it,super comfort and the most I like is that it makes you look super sexy, I really recommend you girls to get yours,

  25. Must Have!!

    Posted by Dee on Sep 6th 2019

    I was a little skeptical about this product. Especially when I took it out the package, it was so small. I thought no way I was getting into it. After 30 minutes, I finally had it on. I had to keep stopping to take a break...lol The second time I put it on was MUCH easier.

    I have bought quite a bit shape wear in the past. I was pleasantly surprised how comfortable it was! Not to mention how it holds you in.

    If you’re on the fence, get off. Definitely get one of these. You pay a little more, but it’s so worth it.

  26. Love it girl

    Posted by myrose613@icloud.com on Sep 4th 2019

    I just had a baby a week ago,&& forsure your shape garment is keeping everything in place. I love it

  27. Worth it!!

    Posted by Johana Gallegos on Sep 2nd 2019

    I Recommended!

  28. Verry happy!

    Posted by Alma Capetillo on Sep 2nd 2019

    I love it, at the first try i was like oh no i ordered the wrong size for me but maybe i was too exited to try it and i rushed my self i took it off and i gave up i was gonna sell it to my sister, second try i was like really surprised because i put it on wit no problem and it felt like the perfect size, so comfortable I'm so happy with my purchase.

  29. Worth it!

    Posted by Jess on Sep 1st 2019

    I love it!!!! I hope they come with one that goes all the way up and flattend the back part and have a strapless bra
    built in!!! Will buy again.

  30. Better than most

    Posted by Nathalie Cobas on Sep 1st 2019

    Happy Butt does what it promises. Kept my belly down and my butt out. It stays in place very good. The only down side I think is that it is extremely difficult to get into. That might also be depending on how you are built. I have very large hips and legs. I needed my husbands help getting it on. The difficulty level makes me not want to wear it everyday. Wish I would have ordered the tank top one. Seems easier to wear I think. But all and all it is worth the price

  31. Best shape wear on the market.

    Posted by Lana Lane on Sep 1st 2019

    I absolutely love it, contours my body in places I'm too lazy to work on. This product is the best definitely worth every penny. True to its size and you don't even feel like your wearing a shape wear plus it doesn't show. I will be recommending it to all my family and friends. Thanks Yahaira for your awesome invention ❤ it.

  32. Great Product

    Posted by Narcy on Aug 29th 2019

    Love how it feels and I can actually breath in it..I think this is exactly what I needed. Thank you Yahaira!

  33. Great product overall

    Posted by Unknown on Aug 28th 2019

    Size: Small (134 lbs) and a M (for my mother)

    PROS: it definitely holds and tightens every mid curve. Great material and it does not flatten your back area.
    The Medium size that my mother wore, she loved. It helped her back pain also. :)

    VERY TIGHT! Hard to put on on the leg sides.
    Tightness caused me upper muscle/back pain. :( But since I only used it once, I needed it to brake? I tried the M size and it was too large on me.
    The wide crotch gusset for when nature calls is not necessary comfortable and it needs improvement. Maybe if the area would open wider, wetting it wouldn't be a concern.
    *Overall I gave it for starts because it is a great product

  34. The best ever!

    Posted by Sherri on Aug 26th 2019

    This shapewear is perfect! I weigh 198 and I got a Large, it fits just right, it’s snug but not to tight that’s it’s uncomfortable. It’s undetectable and doesn’t roll down like other shapewear. I will definitely be buying another one! ❤️

  35. Amazing

    Posted by Unknown on Aug 25th 2019

    Great product! Best out there right now! Only one thing — can you add extra small to the roster!
    These are amazing!

  36. It’s worth it!

    Posted by Lenisha on Aug 23rd 2019

    A coworker had told me about this brand, I was kind of skeptical because I had tried other shape-wear in the past but this one truly is amazing.

  37. Awesome

    Posted by Nicole on Aug 22nd 2019

    It shapewear works awesome! When I first tried it on, I swear it wasn't going to fit, but it did! The only complaint is that after two wears the threading on the bra straps has started to come apart. I am concerned to continue wearing it regularly because I do not want to tear them. It would be such a waste of money.

  38. My enhancer

    Posted by roselyn Mbony on Aug 21st 2019

    Omg l love this. Thank you l will repurchase again all day any day

  39. Worth the price

    Posted by Unknown on Aug 18th 2019

    I was really happy with the product. The only issue I had once I wore it was that the fabric from the crotch were you open it to pee it doesn't close completely and it stays open and uncomfortable. This is my third one I buy from you guys and this is the only issue I have had.

  40. Worth the price

    Posted by Tori on Aug 14th 2019

    This website is so thorough, especially with sizing info. You really can’t go wrong ordering. I was really impressed after receiving my order in only a few days, and then even more impressed with the quality of the product. The smoothing and cinching is much better than Spanx and other brands I’ve previously bought from department stores. I will definitely be buying again!

  41. Amazing
