Find a brass recycler, cover yourself in duct tape with the sticky side out, and have a couple buddies huck you in to one of the bins. Wear whatever comes out with you.

Alternatively, pick up a can of gold-colored Krylon, and shoot your boots. Hang clock innards in place of a kilt pin, and tape a brass plate to the back of your head.

Ok, yes, the theme is getting so mainstream that I'm getting a little cynical ...

So, seriously, you can get a pair of brass-colored goggles from most costume shops for about 10$. You can also just take a pair of swim goggles, mask out the lenses, and hit them with a rattlecan. Bonus points if you use ski-type goggles, like the ones everybody wore around the rebel base on Hoth.

Carry a brass-colored tube with you, and peer through it once in a while. Bonus points if it's really a kaleidoscope (thank goodness for spellcheck!) or a telescope.

Wear a monocle.

Not entirely kidding about the recycler or the brass plate on the back of your head. It really does appear to be that easy.

The kilt is largely incidental.

That's all I got. Keep in mind I'm mostly joking around...make it tasteful, it's a wedding.
