Wearing Irish Sweaters wtih Kilts, Belt or no belt?

[McMurdo]

I've been browsing old threads and just came across this. Where did you find this sweater? It looks like a U.S. Air Force sweater that I remember all the older folks wearing at the reserve base I worked at as a civilian. I've always wanted one because I thought they looked sharp but never knew where to get one since, as a civilian, I couldn't just go down to the BX and buy one.

I recently bought one on eBay the same make as Tobus.
