M.K.
My mom always made awesome, cheap homeade costumes. One year, I was a Christmas present (unfortunantly, I was in the 4th grade, and my old 3rd grade teacher was a Christmas tree, so they made me walk with HER instead of my class for the school parade), one year I was a washing maching (with balloon bubbles), my brother was a crayon (colored sheet and felt hat) but my favorite was Pippi Longstocking (complete with wire in the braids to stick them out!).
Bottom line.....I agree. No way should a tween dress sexier than me!
