Last year we were all pirates. I got their costume from Babies R Us at the last minute and they were marked 50% off.
Maybe next year, I can get some folks together to organize a costume swap between all the parents of multiples clubs. It would certainly save me money but also help the environment by re-wearing costumes.

Costume ideas for twins
My Organized Chaos (edited to add, Tammi put together a huge list of costumes for B/B, B/G,G/G twins. Thanks so much. I think I will be referring to this list for a few more years.)
It is still up in the air about what we are doing this year. Maybe I can still squeeze them into their Thing 1 Thing 2 outfits that I made for their first birthday party. It might be a tight fit but I can always say this is what happens when Thing 1 Thing 2 get into the cookies and cream ice cream.
