I found a store on eBay that sells a tuxedo vest and matching straight tie for $37, with shipping.

I ordered the vest on Wednesday of last week and received it on Friday (shipped from CA to MO).

To start with, after trying it on, I must admit... it looks better without the belt (although it forced me to go digging through drawers looking for my sporran belt because I usually hang it with belt straps).

I like the look of the vest and long tie with the kilt and no jacket. At the very least, it will get me through the summer without having to find the $$ for a jacket.

Sorry, no pictures at the moment; but I'm headed to a wedding in a few weeks, so I should be able to get the wife to shoot a few then.
