  1. Perfect

    Posted by Unknown on Dec 26th 2019

    It is beautifully made. Doesn’t roll up or down. I ordered a large. I wear size 16 pants. I ordered the single tummy layer thinking the double might be uncomfortable. It’s so incredibly comfortable I want the double layer now.

    Posted by Kimberly (kimkillz) on Jun 20th 2019

    I loveeeee wearing this under my dresses or just at home when there’s no company. It’s so lightweight and it compresses the areas needed most without feeling like you are suffocating, meaning I can wear it for hours and feel completely comfortable, I love it thank you so much!

  8. So happy about this product.

    Posted by Amanda R.V. on Jun 15th 2019

    I had ordered the wrong size initially and had contacted them immediately. I received excellent customer service, shipping was fast, and I could honestly say this is the most comfortable shape wear I’ve ever purchased. It enhances my curves but in the most flattering way that I still look like me but but just better :) thank you!

  9. Is worth it

    Posted by merymer Levest on Jun 14th 2019

    I was looking for a undergarment for my wadding dress I couldn’t find it anywhere, my dress is White and plain so everything shows and When I said everything I mean it. I try few different including the ones that they recommend in the bridal salon and believe me none of them works for my dress, after check few reviews and find Yahaira’s single tummy layer, I decided to take the risk and het this one for internet after all it cost $87 and I did not have much time to return it. It is worth it! Every single dollar! I Love this faja and the shape that give me is gorgeous. Thank you Yahaira! You make my day more special because I look the way I imagine in my dress.

  10. Best for Post Surgery

    Posted by Happy Customer Florida on Jun 12th 2019

    I should have had this product sooner. Best for post tummy tuck use. I

  11. Omg so comfortable

    Posted by Valerie Alce on Jun 8th 2019

    I am so impressed at the ability of this product to be so comfortable but yet still give such super tummy control. The other amazing thing is that they don’t roll up when my thigh is rubbing and the top part does not roll down . Every thing stays put . I feel like I hit the lotto in shapewear

  12. New mama feeling flawless

    Posted by Unknown on May 30th 2019

    As a new first time mom, this shapewear had given me the confidence to go out on the town feeling sexy again! I felt so conscious of my belly and lack of waistline since having my baby but now I am going out more and feel so good in my dresses.

  13. Very good

    Posted by Unknown on May 16th 2019

    I did like the product but i should have gotten a smaller size..but overall good product

  14. Perfect

    Posted by Davena on May 9th 2019

    This is exactly what I had been looking for for MANY years, I will definitely be ordering more from this company! Thank you for an amazing product!

  15. The best one!!!

    Posted by Unknown on May 3rd 2019

    I LOVE IT!! fits perfect and I love the mesh on the butt area. This is the best shape garment I have bought its worth the money you spend. I am definitely ordering the double tummy layer. The only negative is that they take a long time to ship. It took them six working days to ship and four days of transition via mail.

  16. Perfect

    Posted by Javi87 on Apr 29th 2019

    This is the most comfortable garment I have ever worn!
    It holds you in completely! No one can tell you’re wearing it!!! Recently got a liposuction done and I wear this garment to work because it’s not noticeable unlike other fajas and it still does the job!
    Will definitely purchase a second one


    Posted by Jessica on Apr 27th 2019

    As a thicker woman having thick thighs and serious booty sits great to find a body shaper like the Happy Butt #7 that fits so snug against my body and makes my booty pop,.AMAZING! The opening so you can use the rest room is the best since we all know how much of a MISSION it is to have to take off the whole thing off then put it back on!!! I would recommend this garment to anyone! Feels comfortable when working out as well! YOU GO YAHAIRA!! I’ll be ordering more for sure

  18. Comfortable

    Posted by Unknown on Apr 5th 2019

    I wore this shaper for 10 hours. I was comfortable and my backside looked great.

  19. Love it

    Posted by Maria Soto Nyc on Mar 27th 2019

    This body shaper faja is everything my butt looks great waistline as well i thinking of buying another one

  20. Amazing Garment!

    Posted by Mayra on Mar 19th 2019

    I received my garment yesterday 3/18/19 and it looked so small. I am 5ft 285lbs and ordered an XL. Luckily I got it on and it felt better than I could’ve imagined! I could actually use a L or the double tummy layer bc in my stomach it wasn’t as tight as I’d like it to be but that is where I am the smallest. Anyways I used it at the gym and I was amazed on how comfortable and how in placed it stayed everywhere as I worked out for over an hour. Totally recommend and will be ordering 2 more!! Thank you Yahaira for this awesome product!!! Customer for life!

  21. Very comfortable

    Posted by Unknown on Mar 14th 2019

    I like how it shapes my butt. The only thing it didn't like was it rolls down from the top.

  22. Surprisingly comfortable

    Posted by Unknown on Mar 12th 2019

    When I first received it I thought, no way my behind is fitting in this, but it did. It was actually easier to get on than similarly shaped shapewear but much more comfortable once it was on properly.

  23. Feels so Great I feel Beautiful

    Posted by Li Li on Mar 4th 2019

    This one finally does not flatten my butt! The material feels fantastic! NO wires or weird material stabbing at my sides. It stretches in all the right places! I can breathe easily! I feel great in it! My Booty looks GREAT in jeans! I want the shorts now!

  24. My butt is happy

    Posted by Sanna on Feb 27th 2019

    I’ve seen many comments and advertising on this happy butt #7. I’ve tried many products in the past with little help to the tummy area plus it wasn’t flattering in the butt region. I’m a mom of 3 with loose skin and with diet and exercise I still can’t get rid of my “kangaroo pouch”. So after about 2 months of research I purchased the product and I’m in absolute AWW with it. My butt looks amazing in my jeans especially my yoga pants, and my tummy doesn’t have that extra roll hanging over when I sit down. If you’re a first time user I’d say the happy butt 7 single layer is best for daily control. I TOTALLY recommend this product to anyone looking for something that is super light fitting, breathable , comfortable and that enhances natural curves! I’m in love! THANK YOU YAHAIRA!!! ♥️

  25. Love it

    Posted by Karen Ormeno on Feb 20th 2019

    Great quality and it’s confortable


    Posted by Tiyonna on Feb 19th 2019

    I really love this product it fits me so well. My stomach is flat my booty looks AMAZING, my leg part doesn’t roll up. But on the other hand the bad part to me is the back part does roll down on me and since I don’t wear a bra I have nothing to clip it too . But overall I love this product and will be buying more.

  27. I love it it’s just as on the add I will be ordering again

    Posted by Reyna on Feb 15th 2019

    This is berry Comfortable it was really nice

  28. awesome

    Posted by Unknown on Dec 11th 2018

    its good & you feel comfortable

  29. If you want it get it!

    Posted by kayla_b_2007@yahoo.com on Sep 17th 2018

    I am very tight with money I spend on myself. But I do not regret purchasing this! It’s defiitely worth it! I’ve been searching for spanks that don’t flatten my butt and here it is! It’s slums and softens every thing out except the booty. It doesn’t necessarily make you look skinnier, it just holds you in and smooths you out while enhancing the curves you have. I wore it to a wedding, and everyone complimented my figure, especially my butt!

  30. Good undergarment

    Posted by Rebecca on Sep 6th 2018

    Happy with my purchase. It does help smooth out lots of lumps & bumbs. Seems to be very comfortable to wear as well. I look forward to using this product.

  31. Thank Goodness For The Pee Pee Hole!!!

    Posted by Tanya W. on Aug 29th 2018

    Yesterday was my first time wearing my product it was amazing it didn’t feel like you were all stuffed up & it was easy to get off. But most importantly I’m on a water pill that makes me go to the bathroom very often so you making that open space to go was amazing thank you o much I will be buying all your items eventually.

  32. the best

    Posted by cassandra catino on Jul 19th 2018

    I would honestly give this company a thousand stars. by far best shape wear I have ever had. and I tried them all from the top brands!!! does what it says. flattens stomach but doesn't flatten your butt.

  33. amazing

    Posted by yesenia on Jun 23rd 2018

  34. So comfortable

    Posted by Unknown on May 14th 2018

    Fits amazing, so comfortable 100% satisfying. I will be ordering again.

  35. Perfect fit and comfortable!

    Posted by Jen on May 9th 2018

    I am 5’6 and 265 pounds (very curvy) and I purchased the XL. This product accentuates all of my curves while flattening my tummy! I love how it’s not super tight on the thigh area, causing bulges, and it is not visible through my clothing. This is an excellent product and well worth the money!

  36. love It

    Posted by Unknown on Apr 20th 2018

  37. I love it!

    Posted by Cynthia on Apr 14th 2018

    Is really confiable and it works perfect I really recommend !!!

  38. Great

    Posted by Unknown on Apr 12th 2018

    Really easy to put on. Very comfortable, did not feel it thought the day.
    Love the quality of the shapewear.
    The only thing I would add to his shapewear would be to be tighter on the tummy, just a little bit, not something that you cant breath! because the shapewear is really comfortable you dont to want to ruin it!

  39. Light but perfect comfort!

    Posted by MyriMend on Apr 7th 2018

    This is my first single layer tummy support and it feels light and comfortable. I normally purchase the double layered but I think I just had a change of heart. I recommend any of Yahaira's outstanding items, the fabric is soft, fits like a glove and incredibly comfortable. No disappointment here, don't think it twice buy your product now!! Thank you Yahaira

  40. Great

    Posted by Jesika on Mar 29th 2018

    This product was very different compared to the products I purchased from different companies . It comes with elastic that holds the shape wear in place. I really loved that it does not flatten my butt giving it the natural appearance ( my butt is natural ) it doesn’t lift your boobs either. Everything natural. It also feels like I have nothing on . After an hour I totally forget that I have it on. I will definitely be purchasing more shape wear products from this company . The small fits me too & I am a size 7 in jeans .

  41. LOVE IT!

    Posted by Unknown on Mar 26th 2018

    Absolutely recommended! I'm around 220 and ordered a size Large. It is so comfortable I even sleep with it on since I'm wearing a cream to tighten my belly. I'm super happy with it and I can't wait to order another one! I love how it enhances your figure and looks under dresses! You won't regret buying it!

  42. happy butt no 7

    Posted by jenny on Mar 19th 2018

  44. The Best BODY shaper

    Posted by Pryncess on Mar 15th 2018

    Hands down the best body shaper I've purchased. No rolls, definately undetected under clothes. Very satisfied with my purchase. I bought this after having my third child and needed my pudge to be flatter. It works. Quality material, and very comforable.
