I wouldn't even need 6 pairs,

the kilts and hose I would take (at this time) would be;
Irelands National - paired with Bottle Green, Black or Beige

American Heritage- Black, Lovat Blue or Dark Red

Saffron - Bottle Green

Only 5 pairs of hose, I'd get them from W. Brewin http://stores.channeladvisor.com/wbsocks/Kilt%20Hose/
They are resonable and fit my fat calves!
