    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.
