I was curious and flipping through eBay for kilts just to see what was available and came up with this:

http://cgi.ebay.com/New-Great-Value-...QQcmdZViewItem

New Great Value Royal Stewart Tartan Scottish Kilt.

Now, there are several different tartans and the write up says:
Brand New Royal Stewart Tartan Kilt

You are buying a brand new Royal Stewart tartan kilt at a lot less than you'd pay in the shops!!

Great for everyday use and excellent value for money.

The features include:

2 leather buckle straps

24" (61cm) Drop

Cotton Lining

Deep Pleats 2.5" (6.cm)

Belt Loops 2.5" (6cm)

100% Acrylic with many features of wool without the itchiness.

SIZE: 42

The waist is 42" (107cm) and the drop is 24" (61cm)

Take a look at the photographs and if you have any questions please ask!!

If you are not happy with your item we will exchange it or refund you the full purchase price minus the postage
Most I can tell about the cheapie eBay kilts is that they are (1) acrylic (2) come in tartans I wouldn't touch personally.

Any comments on these things?
