Skilt

The generic name for a modern or contemporary kilt - often with pockets and made out of fabrics other than tartan.

Possibly a combination of the words Skirt and Kilt.

Used as a brand name by a British kilt maker. http://www.skilt.co.uk

"Hey man, nice Skilt!"

"Are you wearing anything under your Skilt?"
"Shoes and socks..."

"It's not a skirt, it's not a kilt, it's a Skilt."
