  1. LOVE! LOVE!

    Posted by Unknown on Jan 24th 2020

    Love this faja, I just purchased my second one and its amazing. Gives me the perfect hour glass shape and is so seamless under clothes. The only thing is that they NEVER give any discounts especially for returning customers or at all. But overall its perfect!

  2. Best Faja!!!!!

    Posted by Liz on Jan 19th 2020

    This is the best product I have ever owned !! Definitely worth the price

  3. Best shapewear ever

    Posted by Regina Sellers on Jan 19th 2020

    Well I have to admit this is the best shapewear I have ever purchased ever. I will be purchasing more of the shapewear without a doubt.


    Posted by July Molina on Jan 16th 2020

    I love my shape wear !!! You can’t even tell that I’m wearing anything under my clothes

  5. This is real !

    Posted by Taylor figg ! on Jan 12th 2020

    I have been looking for great shape wear and let me tell you ... this is THE BEST !


    Posted by Angelica on Jan 6th 2020

    I was iffy buying this faja.... BUT when I got it and tried it on... I love it and how it fits. It's not tight on the legs and it doesn't hurt your waist. I see reviews that it rolls. I haven't had a problem with it rolling down (yet). I will say be careful putting it on if you have nails or rings on (I took my rings off first)... it gives you a great curves and most importantly it's comfortable.

  7. Finally the perfect shapewear

    Posted by Angelica T on Jan 5th 2020

    This shapewear does exactly what Yahaira explains in her video. It smooths out the thighs and doesn’t flatten the butt. Its also very suprisingly comfortable.

  8. Perfect fit

    Posted by Alma on Nov 25th 2019

    This is the best body shaper I have ever tried. It gives you shape and the best part it’s comfortable. The only issue I have is that the low waste above the knee, the top part on your waste does roll down. And I’m not to happy for that part but above all it fits great m, shapes your body perfectly. Except I do have to keep bringing back up.

  9. Love it

    Posted by Breed on Nov 8th 2019

    Originally I bought it for my wedding dress, all though I have not worn it for that yet I can’t wAit to see it on with my dress, but I have worn it with other pieces and it is the best. It is a little mission to put it on but it’s totally worth it

  10. Absolutely love

    Posted by Jennifer Brujan on Oct 24th 2019

    Does exactly what it says its going todo. My booty is popping definitely accentuates your curves even more :) Love Love Love wish you guys had more sales though ! But over all im happy with it. Will be making more purchases

  11. Perfect shaper

    Posted by stephanie.hernandez03@gmail.com on Oct 17th 2019

    These shapers do take a while to master to get the desired shape but once you get it you will be tucked in. I would love if there was a XS option

  12. Best i have ever used

    Posted by Unknown on Oct 13th 2019

    These spanx r everything!!! They smooth u out tuck u in n r invisible they lift ur butt, n r perfect for crop tops, i wouldnt recommend w dresses just high waisted jeans because it likes 2 fold when u sit down m get back up.... u r better off buying the full one for dresses, i have big thighs n hips n i need 2 breath n this does it all, im 130 a medium gave me that breathable feelin i need, its comfortable n snatches everythin u need n makes it look natural

  13. I love this faja

    Posted by Jennifer Soto on Oct 4th 2019

    I love fajas Ive tried so many butt lifting and this faja is breathable, comfortable, and it really does lift your booty. How ever the waist band does roll down a little bit but you can't really tell when you have clothes on. I got a size large thinking a medium won't fit but I'm definitely buying two more in a medium size. Truly enhances your curves

  14. The best!

    Posted by Jay on Sep 30th 2019

    This is the best shape wear I’ve ever got! Fits right and very comfortable. Will definitely buy again! Thanks yahaira!

  15. Love this product

    Posted by Unknown on Sep 5th 2019

    Omg! Literally the best shape wear out there! Just ordered two more! I am completely obsessed!

  16. I’m impressed

    Posted by Tara on Aug 15th 2019

    Immediately after opening the garment looks nicely made and I was excited to try it on! I bought this product because my wedding is coming up and I want to feel as comfortable with my body in my dress as much as possible. I was really careful putting it on and I was happy with the result. It didn’t flatten my belly all the way but I wasn’t expecting it to, It did however smooth my sides down and felt very comfortable. I’m pleased with my purchase and hope that it will look amazing under my wedding dress.

  17. Love it!!!!!!

    Posted by Darlene on Jul 5th 2019

    Once I received my garmet I took it out of the package and was afraid it wouldn't fit but after watching a YouTube video with a lady who actually showed you how to put it on with out ripping it I put it on the same exact way it was very pleased that it fit great and is comfortable as well. It really makes you butt look good. Thank you Yahaira.....great product!

  18. ❤Biiiiiiiiiittttch!!!! Yeeeeessssss! My ass is POPPING!❤

    Posted by Samantha Mejia Cortez on Jun 26th 2019

    ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤Lol! Let me just say,..........I got a tiny waist, and I'm short, I'm 5"1 and I weigh about 150. All my weight is in my ass and thighs and hips so I struggled for ever to find a faja or any spanx that fit properly and might I add that I could breath in. Lol! I normally wear a size 13 to 15 in pants and I recently got surgery, I got lipo 360 on my abdomen and all around my torso and I got lipo on my inner thighs. I got the Happy but number 7 with the low waist and double tummy layer so that I keep still used high waist Jeans or pencil skirts with it. After lipo this right here was the best body shape I could find. And I've spent at least over 1000 on fajas and shapers and this has been hands down the best. I always wanted it but it was kinda pricey and my cheap ass thought it would be best to buy cheaper ones, and gradually started buying more expensive ones even the Colombian ones but none of them could even compare, the prices were either cheap or to expensive and they never fit properly, I never knew what size to get and would end up with every dang size and still wasnt happy. I was mad as hell and happy too when I put the Happy butt #7 body shaper on. I went all these years looking for something like this and here this was all along. I got a size large and it fits great. I was worried about boldging at the legs or at the top but nope. Aaaaahhh it fits like a glove. I've gotten so many compliments. I have to order another in black to help when I wear black leggings. Ladies, honestly splurge on this, when yahaira said she had the best body shapers, giirrrrllll she wasn't lying. You'll love these body shapers. And for the first time I can honestly say, the size chart is true to size. You wont regret it! ❤❤❤❤❤❤❤❤

  19. Amazing!

    Posted by Unknown on Jun 16th 2019

    This shape wear literally does wonders for me! Immediate buttlift and snatches my waist. Now my sister wants one!!

  20. All smiles

    Posted by Alabama on Jun 11th 2019

    I'm in love with this shaper it's fits real good I just wish on waist was more snatch one my hips are bigger than the other and this shaper even me out so good I will be wearing dresses for the rest of the summer that's what I really bought I couldn't wear dresses because of my hips it holds them real good and lift my I wanna try the shorts like this shaper but I don't know would it help support my hips the only thing that I have about is it's a struggle putting it on takes up time but it worth it yes I recommend this to anyone that's needs some extra boost 6/11/2019

  21. Wow

    Posted by Kiara on Jun 2nd 2019

    This is my first shaper and it’s perfect. My tummy looks so flat and my booty still looks plump. It also so easy to put on!

  22. Me Encantó

    Posted by Blanca on May 16th 2019

  24. Omg

    Posted by Alexis Marie on Apr 30th 2019

    Omg it’s perfect everything I thought it would be it didn’t roll down it didn’t roll up I can’t wait to wear a sundress ❗️

  25. Love it

    Posted by Quasheka Keoner on Apr 20th 2019

    Worth the money!! Will definitely be getting another one

  26. Been thinking about it for a long time

    Posted by Nisa on Apr 9th 2019

    I have my eyes on this for months but I finally decided to go for it. I'm 5'1 125lb I went for M it's really hard to put it on at first but if I would have known I would have got L instead. I don't want it to be too tight L would be perfect next time. I love everything about it. I didn't really care about the stomach part I just want the butt part

  27. Don’t second guess yourself, you NEED this

    Posted by Unknown on Apr 1st 2019

    Only shapewear I’ve ever owned that delivers on every single promise it makes. My butt has never looked better and it is completely undectectable under my clothes. AND it’s actually comfortable! Would give 6 stars if I could!

  28. Absolute perfection!!

    Posted by ahurtado3804@ymail.com on Mar 28th 2019

    As soon as I received this garment I tried it on. And... oh my god! My waist went from 26 inches to about 24.5. It’s incredibly comfortable. Don’t think about it, just buy it.

  29. You Better Get You One Or Two

    Posted by Ms.ladybug on Mar 26th 2019

    I am a shape ware kind of girl and I absolutely recommend this for any lady that loves to look fabulous at all times.

  30. Love it!!!

    Posted by Daniela Chirinos on Mar 19th 2019

    so amazing!! makes my butt look like Kim K's LOL

  31. In love with this product! ❤️

    Posted by Wendoly Leon on Sep 12th 2018

    I'm 5'2 and 151 lbs I order size medium which fits perfectly on my body, I recently lost weight and this shaper is what I was looking for, it holds and shapes my curves and I proudly go around receiving tons of compliments on my body shape... Worth every single penie

  32. Awesome

    Posted by Unknown on Aug 31st 2018

    I ordered a large do to not being able to decide. And it fits wonderful I could have gotten the med though. But it feels great and it does not ride up on the leg

  33. A must have

    Posted by Palladinodoll_Tisha on Aug 6th 2018

    I recently had lipo360 wBBL I’m 5’5 187 waist 32 hips a 49, I’m really think in the hip & butt area. I chose this garment bcs I need to wear something sexy for a special event & my faja was very noticeable. This garment is amazing it gives great compression.I didn’t roll at all, it was completely unnoticeable under my high waist skirt .It lifts your butt so well and doing so without smashing it... I’m going to order the garment that comes right under the breast as well

  34. Exactly as described

    Posted by Gina on Jul 23rd 2018

    I’m 5’6 150lbs. Big thighs, good size butt. I order it because I have to wear a faja because my inner thighs touch so when I wear a dress I HAVE TO wear one. I have tried so many of them but they indeed flatten your butt. I got the medium and the large one and to my opinion the large one works better for me. But they feel great and look great. I highly recommend it.
