Real Feedback From Men Wearing Slimming Shirts to Formal Events
"Honestly I was skeptical about wearing shapewear under a suit, but I had this work event coming up and I didn't want my gut showing in the photos. The vest stayed put the whole night — even through dinner and a few drinks — and I kept forgetting I had it on. That's the part that surprised me the most."
