    Average for belly shaping, great for butt lift and tight compression

    Posted by Katherine on May 31st 2023

    Customer service was very responsive to my request and helped me right away. The shapewear fits great under the bra and it does lift the butt, unfortunately, it doesn't compress my belly. Even though I'm thin, my belly looks more rounded than usual in a tight dress. I should have ordered a double or triple tummy layer, but it seemed like a single layer was enough. I would recommend more compression in the belly if you want to wear tight dresses or you're looking to hide the muffin top.

    I have wasted so much money over the years trying to test out different fajas (shapers) to no avail. I spent more $$$ on kim k's fajas and they rolled down and hurt my vag area too. but yahaira's SINGLE TUMMY LAYER FAJA IS EVERYTHING AND MORE! If you are having second guesses about buying DONT! GET THIS ASAP! I had to leave a review because its that good.... im 5' 4" and 175 lbs (size 12) and got the medium and it fits perfectly =) HIGHLY RECOMMEND...they do not roll up or down, they have an opening in the crotch area and lift your butt up too =) whewwwww
