Here are some of mine:

This is my Grim Reaper costume. I wore this in college and scared 200 lb line-backers with it. Yay! It's one of my favourite costumes.

This was my witch costume in 2006... can't see it very well in this shot, but it's my fave photo from that year.

It was Persians for us in 2007. Hubby picked the theme.... Drove me nuts too. I barely finished sewing the danged costume before Halloween!

This was hubby in his Persian costume. =)
