Perry SuspendersPerry Suspenders Men's Elastic 2 Inch Wide Hook End Suspenders (Tall Available)

Can they be worn next to your skin? I only wear untucked t-shirts with CCW and when it's hot I don't want to wear an undershirt under a t-shirt

My belt is 1-3/8" wide and the rear clip doesn't stay hooked. A safety pin attached to the pants works. Do you have any other suggestions?

Will,they hook onto a thick 1.75 inch belt?
