depends on the girl shirt.
most are too short and end at navel level. i hate that.
not because i'm fat but i simply feel uncomfortable, apart from the fact that it looks like some disco babe cloth, only in black.
no thanks.
but luckily there are girl shirts of regular length too, and those simply rock
i don't like the shabby look of a woman wearing (X)L men's band shirt.
sure i have those too, but i seldom wear them.
additionally, most girl shirts look better anyway: the design is more appealing: taylored to a woman's shape, simpler in looks (only a logo or symbol or a short sentence, but not the tourplan, the albumcover, and other stuff that just gives a too overloaded impression);
the collar area is not so close to the ...well collar/neck so I don't have the feeling that something/someone's too close to my throat...
so all thumbs up for girl shirts of regular dimensions
one annoyance however is, that girl shirts are mainly presented in S and M.
S is teenager size up to 14 and M is teenager size up to 18 :Smug:
there are not so often L shirts, but fortunately it happens that all bands i wanted a shirt from did have girl's L.
yay
