Too short?
 

Not for me!!!

Is there such a thing as a skirt that is too short?

You are talking about her hair, aren't you?:D

Yes!
 

If you spend time in the Subway when the Bridge and Tunnel Crowd is in town...

Of course, I guess the question then becomes if the skirt is too short, or if the girl in question simply should not be wearing it. Which further suggests that they should not make said skirt in said size. Therefore the skirt is too short.

EDIT: I definitely don't mean that the shirt in the OP is too short, though!

I wish they used to dress this way in HS!
