Alright this is my favorite movie so that is probably the only reason I noticed this...close to the beginning of the movie little after the graduation shots scene,it moves outside...Allison (Amy Locaine) says "I'm so tired of being good" and starts to walk over to Crybaby (Johnny Depp) and his gang (Ricki Lake, Tracy Lords, etc.). In comes Lenora (the redhead) you see the first shot of her, note which side her hair clip is on. Then the shot goes to Crybaby I believe either that or another shot of Allison...its been a while. Back to Lenora. The hairclip is now on the other side of her head.
