    Open Bust Above Knee Couble Tummy Layer

    Posted by Beth on Oct 14th 2023

    I'm really impressed with the quality of this product. It is a must have staple in any woman's wardrobe. I suggest getting your exact size and if your shorter going with a size below your actual size. So if you're a Large go with a Medium. Example: Shoulder straps may be too long measuring from torso to the top of your shoulders. The straps are adjustable but still a bit long. I'm 5'4" and 186 lbs. and got a Large and had to exchange for a Medium. The fabric is really really good as it has a nice stretch but still cinches you in. Excellent and durable quality. A must have faja.

    Best Shaper I’ve tried. I have purchased the one where you hook straps to your bra but it felt like a hassle every time putting the straps on and off so I went with this one and it is my favorite so far! I highly recommend

    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.

    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 ❤️
