I only do laundry once a week, so I usually re-wear my jeans and stuff. I think that's the reason why so many of my jeans shrank so fast. That and my dryer seems to shrink clothes a lot faster (it's old).
As far as t-shirts go, I usually wear them twice and then throw them in the washer. I sweat sometimes at work since I do shipment so they get gross fast. Living in a humid state doesn't help either.
Sweaters I don't get a chance to wear, so I don't wash them much. They don't get that dirty. Working in a clothing store has made me not want to do anything with clothes as far as washing and putting away xD. I have a lot of sweaters that I end up stretching in the arms because I roll my sleeves up, and the torso because I'm constantly pulling on it to let air in. Throwing those sweaters in the dryer is one of the few times I appreciate my clothes shrinking, I always stretch them out!
By the way, your sig is from that movie "Legend" right? I've been trying to track it down for awhile now because I remember seeing it once a LONG time ago, and if I remember it's roughly Zelda the movie, ferry boy fights evil demon. Well I'm sure that's the premise to a LOT of stories, but yeah, tight sig. I think I heard a rumor that that's Tim Curry who plays the demon guy.
