    shape wear

    Posted by Denesha on May 10th 2023

    i love love this product, this is like my 5th shapewear, my only issue with the product is the end rolls up th silicone on the bottom could be stronger. However, if you are looking for comfort, seamless and durability this is the shapewaer. it makes my bum looks amazing.

    Best Faja EVER!!!!!!!!!

    Posted by Judi on Apr 30th 2023

    I bought this a few years ago, never wore it because… who knows what matters is that I started wearing them because yes I have like 3 different ones, and I have to say of all the shapewear I have ever bought and trust me I have bought a lot. This one is hands down thee best of them all. All these years later I am glad I got it. It tucks you in, in all the right places while smoothing everything out. My husband complemented me on my “new pants” not realizing all I did was wear the shapewear. Hands down my favorite shapewear moving forward.

    Fits like a glove! Second time ordering and I definitely recommend paying extra for fast shipping. Packaging is top notch with instructions on washing , etc.

    The amount of confidence I have in this Faja is absolutely unbelievable and unmatched. It’s giving BBL lol, no but seriously it highlights all the right areas, especially the booty. I also really like how the straps go over the shoulders allowing the back area to be tight and in place. The open bust is awesome because it still flatters the breast area. Honestly, a solid 10/10 for me. Definitely wearing this one regularly. I got my eye on the low waist Happy butt no.7 shorts next for summer ! Thank you so much, I love it ❤️

    Not as much booty lift

    Posted by Aziza on May 21st 2022

    Don’t get me wrong, I love this product but it didn’t have as much booty lift and definition as the happy butt 7 high waist capri. I have lost a little weight and since the sizing recommended to go up if you’re in between sizes it also isn’t as much compression as I would like. But over all it does the job and is great quality. The leg gussets are much improved. My happy butt number 7 high waist capri gel grip in the leg gusset is wearing off and this new product seems longer lasting. It’s definitely worth it.
