Had to get up and go count my t-shirts; have 14 but most are worn when I do yard work. When they get to worn I toss them. Same with blue jeans; I'll wear until pretty well worn out.

Interesting to see what folks like and enjoy collecting.
I have my doll collection(about 300+) and also collect owls but prefer one's that are more on the humorous side and only have about 30.
Have a lot of VHS tapes(I think only about a 100) that I most likely won't part with.

Only 15 T-shirts? You are just a beginner!

Actually I do wear them out pretty fast.
