It's funny, cause he gave example "You dress up like Cher".Magnum pisze:Well, yeah, "dressing up" means you are either dressing in something elegant or you are dressing up as someone (heh, used that word in the explanation), so like dressing up as Wenger for Halloween. I thought you understood that and just did not know why we use that.
It would sounds strange if I will say vice versa? I mean "I will dress something special for dinner".
