"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."
"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!"
"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."
"Sized up which was necessary for an overall good fit. The neck piece is sticking out in the back unfortunately, became way too large. Zip and quality feels good, I’m glad a sports bra underneath is not necessary due to the padding"
"Love it so much!!!"
"I love that it snatches the body so well, but the zip has a default on my product. Sometimes the zip will just split in two, so I’m really scared to wear it outside of my house."
"Runs small and it's really compressive. Had to size up."
