When you buy a pair of pants or a shirt, how long do you keep them before getting rid of them and buying new ones? I have 2 t-shirts that I bought 7-8 years ago that I still wear. Most of my shirts last about 4-5 years and pants last about 2-3 years. I usually only get rid of them if they start getting holes or if it's something that I just don't really wear anymore. I donate most of them to good will and throw away the ones in really bad shape.
