    First off, this is my 2nd purchase and I gotta tell ya, this shape wear is by far the best I have ever gotten! Don’t hesitate to order. Let me tell y’all about the customer service….. PHENOMENAL!!! My mail carrier made a mishap and unfortunately didn’t ship my package to the correct place, I contacted Shop Yahara and the customer service team and they were ALL OVER IT!! From beginning to the end, just the care means so much!! Thank you for truly helping me for sure!!!

    Low Waist above knee

    Posted by SW on Sep 20th 2023

    I really like this product ,it smooths me out without feeling tight. My only complaint is the bottom of the legs roll up,. I believe if the grip Inside wasn’t there it would cut down the rolling, I hope the company do more to stop the rolling up

    Best shaperwear ever hands down!!! The difference this garment makes is night and day. I have this shaper wear in the knee and the shorter version which I wear with shorts. I wear this one with pants and longer dresses. This shaper has become part of my routine. It flattens my tummy while the mesh material on the butt keeps it perky. You must try this!

    Best faja I’ve purchased

    Posted by Alejandrina Vasquez on Oct 9th 2022

    Im getting married soon and was on the market for a good faja. A friend of mine recommended Yahaira to me and I ordered the high waist double tummy layer! I fell in love so much with this faja that I went on the bride to be Facebook group I’m part of to recommend it to all the girls! Unfortunately a week later I lost it after my cousin wedding! I decided to order another one but this time the low waist because I thought it would be more comfortable under my wedding dress. I wore it last night for the first time and it was just as comfortable and perfect as the high waist! I can’t recommend this faja enough!!! Even my fiancé said it looked like it got a bbl when I put it under a fitted dress! Love love love this faja

    Happy Butt Low Waist Above the Knee

    Posted by jenny on Aug 12th 2022

    At first I was extremely happy with the garment. It did exactly what it claimed to do. After the first wear however, the back silicone/rubbery portion on the waste band is lifting & looks a dingy color. The front silicone/rubbery portion of the waist band does not look like the back. Not sure what's going on? The rest of the garment is perfect though.
