I'm invited to an upcoming costume party (roughly 50 USD, all u can drink).

I have roughly 10 days to prepare a costume.

I haven't decided on wt to dress up as yet, anything that's not a Roman will do. I'm a busy clerical slave with ridiculously long hours for ridiculously low pay, so I cannot afford the money/time for something awfully expensive/time-consuming. (so no maille-knitting or antique swords)

Any suggestions?

p.s. (how hard is it to glue cloth together to make a fake linothorax?)
