Lmao, Audrey, I love your costume. I think it's perfect if you act exactly like that as in the pictures. And go "ARRGGHHH!!!!" Hehe, those pictures made my day.

I think cutting the sleeves would look... odd... If you cut the collar off on that shirt, it'd be weird too, but if it wasn't so dressy of a shirt (without the buttons and the look of it being just ironed) I'd say go for it. I wish I could think of the fabric name, but we used it in a musical.. but the point is.. with THAT shirt, leave it as is.
