I wear the kilt everyday! It is my "normal" clothing, so it would not be part of a costume.

And I hate pants!

If I were going to go to a halloween party and still wanted to free myself from those hated cloth tubes (THCT) then I would just cut up a cheap sheet, and make myself into an arab.

Or go as a south sea islander.

Or a budist monk.

Or - well you get the idea.
