"Love love love this product, super top, the quality of all the product, I love it so hard, also want it in more colors. The zipper works good"
"The padding inside the tank is such a great design! The length of the tank makes your leg look longer."
"This top is everything I’ve been looking for! Great amount of coverage, good support, and gives a nice shape. Only issue is that the material is slightly too small around the armpits so I do need to pull the top down a fair bit as it rides up into my pits. I’m 5’8 for reference and got a small."
"This built-in bra tank is so pretty, but the sizing is way off. I sized up and it still feels way too compressed and tight."
"This is been my favorite purchase so far! The fit is so flattering. I feel like a Bond girl who attends Pilates. Lol I wish it came in more colors!"
"Love the compression I am usually a medium sometime a large and got a medium and it was extra compression, probably would get large for normal compression. none the less love the material and the look! would buy again in large!"
"Very stiff"
"The fabric is so comfy and it’s so stable and also sexy"
"Sucks you in without being uncomfortable. So flattering on the shoulders and neckline. 10/10."
"I originally ordered a size S (my usual size) but when it arrived it was a bit too snug. A size medium was perfect for me and I love the thick material and how warm it keeps me while still allowing for movement. Absolutely love how flattering this top is."
