Get suspenders. Being skinny with no ass is a problem, but being fat with no ass is even worse. You can get the kind that go under your shirt if you want to wear untucked shirts or you don't want people to see them. It's life changing after spending years with either your jeans or your belt being so tight that you're in pain all day and people are still seeing your ass crack constantly. Yes it means you're getting old, but honestly, you're not fooling anyone about that anyway and we're all tired of looking at your butt crack.
Upfitter® belt-loop suspenders for men from HIKERS® Co. Buckle-less design, worn under or over your shirt, with removable, washable nylon hooks.
