Okay, so I was skeptical at first - a shirt that claims to slim you instantly? Sounds too good to be true. But after wearing this for a couple weeks, I'm actually impressed!
The fabric is super stretchy yet firm. First time putting it on was a struggle (felt like wrestling an octopus), but once it's on, it does give that 'snatched' look under clothes. My dress shirts suddenly fit way better.
Biggest win? The back support! I sit at a desk all day and this actually helps my posture without feeling like a medieval torture device. The criss-cross panels are genius.
Few things to note: 1) Don't expect magic - it compresses but doesn't actually burn fat (duh). 2) The white version bleeds color in wash (learned that the hard way). 3) The arm holes can ride up if you're super active.
For the price, it's way better than those expensive shapewear brands. Just size down if you want serious compression. Would I buy again? Already did - got one in black too!
