No way dude, you never get too old. I am 39 and I went to a party as a greaser last year. Who cares what others think. It is all about you being a kid again and enjoying the best holiday of them all.
A zombie greaser? lol. I actually was thinking of being one of those....OMG, I thought you were going to type that your were 70 and I was going "Awwww! He's going to be ADORABLE as a greaser!!!"
You picked a great costume, I'd go with it whole hog and if you wanted to be one of the characters that dies (???: I haven't read The Outsiders yet) that wouldn't be a bad idea either! Because even if someone doesn't know who Soda Pop is, they'll just figure you were the leader of the pack and rode your bike off Dead Man's Cliff. Either way, awesome costume. You must post photos!!
Ha. I was actually thinking of doing that, and have been looking for retro Mickey Mouse shirts.I am a big fan of S.E. Hinton myself and "The Outsiders" was a classic movie! You aren't too old AT ALL!!! I love the fact that you're doing a "tribute" to Swayze (he was a Texas boy, after all!), but if you find an old Mickey Mouse shirt you can do the whole Two-Bit Matthews thing, as well....
