If you hadn’t heard the incredible buzz (including on Good Morning America!), the first-ever National Costume Swap Day is already a wild success.

With more than 65 registered costume swaps in the U.S. and Canada, there’s a lot of money and landfill space to be saved this year. Plus, swapping costumes is FUN!

Are you planning on attending a costume swap ?

Green Halloween® is a nationwide non-profit initiative started by mother-daughter team Corey Colwell-Lipson and Lynn Colwell. In 2010, Green Halloween became a program of EcoMom® Alliance and has events in cities across the U.S.

I’ve been so excited to hear about all of the people organizing costume swaps. Everywhere I turn, I’m told that neighborhoods, churches, organizations, schools and groups of friends are finding ways to put “Reduce, Reuse & Recycle” into Halloween action.

High-five to everyone.

But it suddenly struck me: Halloween is the second biggest holiday (after Christmas) for consumer spending on decorative items (in 2008 Americans are expected to spend 1.58 billion on decor alone). That’s almost as much as we spend on costumes (2.1 billion). We should be having decor swaps as well!
