Most of them. I have a few regular girl shirts... the tank tops usually fit alright, but I've never seen any woman look good in a babydoll tshirt.
And I don't mind the occasional Is/Isa/Issy/Izzy, but it gets annoying when people just assume that I want a nickname and constantly use it to refer to me.
Yeah, they tend to shrink bad. If I ever buy another it will only be washed in cold water and never dried in the dryer. I've got a long torso to begin with, so shrunken babydoll shirts = bad. Except for Derick's entertainment, of course.
