K or S?

[bittenbefore.livejournal.com]

Hi all
I figure this might be crafty cos i promise to post pics and how-tos when i complete the costume!
My friend's throwing a costume party and i need to go as something that begins with K or S. My boyfriend's going as well so male or female costume suggestions will be appreciated [so far i have sailor, schoolgirl, superman,spiderman suggestions]

And just so the post is craft[ier]

Here's a bag i made ages ago from a McCalls pattern.

Thanks in advance!
