look, it's not magic. you're not gonna put this on and suddenly have a six-pack. but it smooths things out. makes your clothes fit better. gives you a little boost when you need it. for me that's worth it.
used to dread the office holiday party. the suit, the photos, sucking in my stomach for four hours straight. wore this under my sweater this year. my boss's wife asked if i'd been "working with a trainer". i just laughed.
I dropped about 45lbs last year. was feeling good until i saw the loose skin around my belly in the mirror. kinda crushed me tbh. My sister��she's the one who found this vest. Tried it on and�� man. Actually smiled at myself. Wore it to a family thing and didn't hide from the camera for once.
so i'm at the gym, right? on the treadmill, and i can feel everything jiggling. hated it. this vest locks it all in��not like a corset, just�� snug. ran 5K yesterday, no jiggle, no chafing. forgot i had it on halfway through.
my dad. he's 60-something, retired. never cared about clothes. but lately i could tell he felt�� off. got him this vest. he called me after trying it under his sunday suit. said he stood in front of the mirror for like ten minutes. haven't heard him that happy in a while.
