Being fairly new to the joys owning a feileadh-beag, I have a question regarding the length of a kilt, especially in the current economic climate...and yes, I'm goig to admit to my ignorance on the issue, but if you don't ask..

Many makers sell both 5yd 'casual' and 8yd 'dress' kilts. Is it really worth buying both lengths?

I've seen the full length kilts worn both casually and formally, so aside from the issue of cost, what are the reasons for owning the shorter kilt as well as the full length?

I know the 8yd kilt can be VERY warm (hired one for my wedding reception, and boy did I feel the heat!), so would the 5yd be more for warmer weather? Or just for 'slumming it'?
