We bought Edie a second hand monkey costume about a month and a half ago in the 6-12mo size thinking it was baggy and would fit despite being 14 months old. It was very cute. It had a felt banana sewn into the pocket!
Except then she outgrew it.
Thankfully we'd also purchased a "skeleton suit", which was a low maintenance alternative (I think meant to be a set of pajamas) that probably allowed Edie to be happier than the mandatory monkey-hood the earlier option required (Edie is not so much the fan of hats and hoods).
We had a lovely halloween with slightly warmer temperatures than expected, actual sunshine, and more importantly, NO RAIN (it's been a bit of a monsoon this last week). We visited the Fremont and Ballard markets, ate chowder and fish and chips at Ivars, I winterized the yard while Edie took a delicious 2+ hour nap (and Jeff took a short Vespa ride), we briefly visited Edie's great grandma in Seattle, and then we trick or treated at a few neighbor's houses (her first trick or treat experience!). She loved it. She did try to run into our neighbor's house when they opened the door, but thankfully she (the neighbor that is) found it charming.
