We were invited for Halloween party at my friend's sister house and we came underdressed. The SMS invitation stated 'costume required' and we party-blooped into the house with normal clothes. They didn't use any EO and they did all the decor themselves, which reminds me that I should get their vendors and share with you guys ;)
There's a children corner with table of fun stuff for them to play with, and a section of story telling space. It was all spooky fun but Baby J was too tired to socialize so we had to excuse ourselves early.
