No, I get it. If you're not a standard couple you want the costumes to match in theme. I get you, my dear. I am well versed in LL speak.

Isn't it great when you have a friend who knows how to correctly interpret you? I know you do that with me a lot, and I so appreciate it.
Anyhoo! Enough of the TK / LL love fest.
Have you thought about non Disney themes?
Anthony and Cleopatra.
Greek Gods / Goddesses.
Pirate Wench / Pirate Captain.
Or if you want to go Disney with it, there's really simple ways to make certain costumes as opposed to buying them, like the Wall E and Even costumes I made for my mom and DS last year.
