Ryan karaoke'ing during the Shitshow Mardi Gras night. Granted, most guys aren't in this skimpy of gear, but I say go for it!!
For guys, just beads really! And be prepared to give them all away! Masks are a pain in the arse. When we did a Mardi Gras night, we couldn't find beads anywhere. In the end, we bought up a load of those long christmas tree 'beads on a string' decorations, cut them to necklace-sized lengths and twisted the two end beads together to make a necklace. Worked really well and we had literally 100 necklaces to hand out for around £7 for the lot.
I was gonna say wear your wife's purple sequined hot shorts with beads, mask and a crown, but I see she best me to it with a pic. :huh:
