Yes, Thats a Sweater

I got a box in the mail from FCUK (a lovely but sort of strange kimono sweater thing) and while i was holding the box under one arm a co-worker asked how i liked my new sweater. "um. how do you know i even bought a sweater?" Oh. Apparently they label all their mailing boxes...but what happens if they run out of "sweater" boxes and need to send the item in a "pants" box?
