an 11-year-old girl... should be wearing.... purple booty shorts, black leggings, a completely see through green シャツ and a black strapless bra (she doesn't have very big boobs) and Hightops out to a museum????
NO ONE should be wearing booty shorts in the first place, unless it's summertime and you're a girl who thinks you're better than everyone else for no reason. Well, that または Alois Trancy but that's another story. Anyway, that's a big fat no.
