Update: First time I washed them, I put them in the dryer for about 10 minutes and then air dried them. Thankfully, they didn't shrink (at least not noticeably)! Since then, I haven't put them in the dryer at all; air drying them has, actually gotten most of the wrinkles out, which definitely isn't the case with my other non-iron shirts. I'd give the fit a B+ but that has nothing to do with washing/drying them... Thanks for the advice, folks!
