Okay, so I bought this backless bodysuit for a wedding and... it's complicated. The cups? AMAZING. As a 34D, I got serious lift without feeling strangled. The adjustable straps actually worked with my tricky backless dress - miracle!
BUT (why is there always a but?) the torso part was a disaster. I'm 5'7" and it kept riding up like it was trying to escape. The "slimming effect" turned into "visible panty lines from hell" under my satin dress. Not the vibe.
Pro tip: The open crotch design is genius for bathroom breaks at events. No wrestling match required. Though I wish the crotch had snaps - it shifted when I danced.
Final verdict? 3.5/5. Perfect for cleavage, fails at tummy control. Would rebuy just for the chest support but size up if you're tall!
