    the over fit was great , but I cannot stand the straps that go over the shoulder they dig into the armpits and so uncomfortable I also have they one that you attach to your bra and that is a pain to do,I have to have help to get the strap around the back of my bra and then to remove too

    Love this brand! Obsessed with the product. Will never switch up

    So, I recently lost over 200 lbs and have been going through surgeries the last two years to tighten my skin back up, including bbls, tummy tucks, back lifts, etc. and let me tell you, I have time and time again came back to Yahaira’s products. Without fail, they last a while (even though I wear them everyday) and comfortably, while also seamlessly shape and SNATCH my body/butt. I recommend this product to anyone considering it. You will not be disappointed!

    I am in love with shopyahaira fajas. This is my 5th one. I have a few in different styles. These are the best. The flatten what the tummy and not the butt. And that is what makes it so wonderful and amazing.
