I wear the Sit-Tight Belt everyday. This belt has been the best shirt stay I've worn. It always keeps my dress shirt tucked in and tight. It works for polo shirts too.
This product is the thing that separates the real gentlemen from the ordinary ones.
I have always been self-conscious about my appearance at work because I always have to readjust my dress shirt every time I stand up. This product completely solves this problem and I wear it everyday!
