There are two pictured on the right, post 6 of this thread. Combined with the too-long kilts they look pretty much like what I expect they are -- guys who have no clue about kilt-wearing and just have it on for the day/for a laugh/whatever.

I'm with Chas on this one, scrunched hose and boots pass muster. Sandals (see Riverkilt, for example) can work. Derek pulls off the Chucks-and-hose look with great regularity.

But I think balance and proportion are key, and to my eye thin short little socks just don't work.
