Hi,

'Edinburgh Woollen Mills', here in the UK, is a chain of High Street shops selling mainly women's clothing, but each branch has a small men's section (usually tucked away at the back!). Over the years I have bought many a good pullover and brushed-cotton shirt from them, but I have yet to see any men's kilts on the rails. Women's tartan skirts yes, but men's kilts no.

From your description, I'd say you have a skirt there - maybe a kilted skirt, but a skirt nonetheless. Time to get the needle and thread out!!
