Wellington Sevens - costume suggestions required

I know we (3 guys, 3 girls) are probably leaving it a bit late BUT we are keen (I said we ARE keen people!) to dress up for the Wellington Sevens this Waitangi weekend.

We've had thoughts about cartoon characters, TV programmes, movies, sports teams, rock/pop bands, characters from literature ...

More specifically: Netballers, double the Three Musketteers, Roman/Greek/Nordic/Babylonian (LOTR) warriors ...

So, suggestions
