    AMAZING but fell short after a short time

    Posted by Brittny on Jun 2nd 2023

    This is the best shapewear I have ever had. I have custom made fajas that are not as good as the Yahaira double layer. This snatches every inch of stomach pudge and plumps your butt. It gives instant BBL. My only issue is that I’ve had it for 6 months and the legs are starting to roll up. The adhesive has completely frayed. It’s devastating as I only hand wash and very delicately. Contemplating ordering another…

    This faja is amazing. Makes you look like you got a BBL without spending all the money. Don’t think twice about it. Just buy it!!!

    Posted by Misty on May 14th 2023

    Fantastic! Fits great! Im a 14 and I got a XXL. I know it says to get large but I was afraid it was going to be too small. This size actually fits. Holds me in, love the straps and doesn't roll down or legs dont come up. Great product

    happy butt NO.7

    Posted by Tri on Apr 27th 2023

    so let me start by saying shipping is fast, packaging is cute and you get info about shapewear before trying on, cool!! BUT this shapewear doesn't compress the stomach, it does make the booty look good buttt if you have a fupa, muffintop, flat tire whatever you wanna call it , it will still bulge in this shapewear it's smooths but doesn't compress so you still look fat. i wanted to like this shapewear soooooo much after buying countless shapewear , this honestly compares to my shapewear i recently got from target for $40, same style minus the straps that clip to your bra, overall if you have a lil gut this may suck it in , if you have a bigger midsection it doesn't compress or flatten at all, your butt will just look good while so. i could've kept my $97& continued with my target shapewear. don't believe the hype, i've watched all the reviews and videos on it all over youtube, if you don't already kind of have a flat stomach this isn't gonna do much for you, no one will notice your wearing it that's how much of a difference it DOESNT make.

    Rolls down

    Posted by Sporter on Jan 28th 2023

    I really love this shapewear. Compression is amazing and definitely adds a lift to the butt. The only complaint I have is that it rolls down. But I suppose that problem was solved by the straps you attach to the bra. However, it would be nice to be able to wear the shaper without the straps.

    Best shaper ever

    Posted by Cece on Jan 13th 2023

    Ive had a couple shapers and this shaper actually does what it said it would. It lifts your natural glutes without looking weird and clumpy smoothens and tightens your stomach area and keeps you from jiggling everywhere. I would buy it again. It is very fragile and takes some time to put on as it’s pretty tight but once it’s on it fights your body nicely and is very comfortable to wear all day and every day.
