I found it!!

Collin is going to be a Sea Otter for Halloween! It is the cutest little costume ever! Thanks to all everyone for the referral to BuyCostumes.com It was a great site with tons of costumes and all sizes. I did have to get a 3T however since I waited til the last minute..that's okay. He can wear it again! hahah
Shipping was only $1.99 and it is guaranteed to arrive by the 28th. I figure it will most likely arrive beforehand, but if not, it's still a few days prior to the festivities! This is the last year I am going to be able to dress him cute (and I LOVE animal costumes) so I decided to get this one. It was between the Meerkat, Ring-tailed Lemur, and the Sea Otter. I got the Otter because it was plush-like while the others were more fleece-y. I can't wait to post pics of him! He is going to have fun and be warm and cuddly!
