Usually it is just people saying that I look interesting and that they wish they could dress however they wanted. Sometimes I get weird comments about popular media, asking if I am cosplaying or going to a party dressed as -insert popular character here- (the weirdest one was some lady asking me if I was cosplaying Elsa, to which the man she was with laughed and said "She is clearly a valkyrie!").
People tend to just mention that my apron dress/wool dress is pretty, or comment on my jewelry, or ask where I got/how I made part of my reenactment clothing though.
I mostly just smile and go about my day. I'd take weird comments if it meant I could be this comfortable forever. Nothing is more comfortable to me, clothing-wise.
