We are going to the Mickey Mouse Halloween party at Disneyworld next month. For the last 2 weeks, DS keeps saying he wants to be Mickey Mouse. I really don't like the costumes online and I want something lightweight and easy to remove for potty breaks (ideally bottoms separate from top).

Anyway, I have been doing my research on how Mickey dresses (pathetic that I do this instead of paying bills). He is all black (legs ad arms) with red shorts that have white buttons. And then he has huge yellow shoes. My question is...

Can I just put DS in black long underwear with a pair of red shorts and sew on some white buttons? He would wear his ears and I could pin on a tail on his rear end. Is this tacky or will it do just fine for the Halloween party at Disneyworld?

Any other creative ideas?
