Haha! Brilliant! I really want to put together Rose’s outfit from the Empty child eps, as a “get away with it in public” outfit. Also her 1950’s dress from The Idiot’s Lantern to go with hubby’s Tennant suit.
Costumes are required and no cameras… is this an Eyes Wide Shut themed party? 
Edit: I’m nearly certain if I show up with only a camera I’ll be kicked out…
Well sure! Wearing ONLY a camera it’s awfully difficult to cover things necessary to be socially acceptable in public 
I must say, it was a fun and rather tame party. I had fun by basically sitting back and watching everyone else have fun (that’s how I have fun at parties). I think I was the only one that didn’t drink.
What did you end up going with? Pics?
I went with a variant of Mister Fixer. Jeans, steel toe boots, white t-shirt (didn’t have time to get a Gi), blue RC hat, white belt, and masking tape wrapped around both hands. My “date” went as Wonder Woman (the variant who wears black pants). Other people include No Face (or something like that), Major Hues in civilian clothes, standard Japanese female school uniform, a bunny dragon, the guy from Castlevania, a duck, a white belt karate, and Victorique de Blois.
Wolverine in his white tee and jeans maybe?
Just put some effort into crafting some claw accessories.
Or, I think you can buy them? Probably kind of pricey for a good set.
Got a leather jacket? Get someone to stitch on an X symbol.
