Men's Thin Vest Underwear

[Bust Adjustment] The bust area features a double-layered fabric compression design, effectively preventing sagging, shaping the overall bust, and avoiding a feminized chest.
Abdomen Adjustment: The mid-section uses a double-layered fabric to enhance abdominal tightening and hide a "small belly."

[Suitable for Various Occasions] Can be worn as an undergarment when going out, maintaining a neat look while subtly shaping the body; also suitable for casual daily activities like staying at home, exercising, and working.
