Pikeur…
Pikeur makes a number of different coat fabrics; the ones we often use here in SoCal is called the lightweight wool and it has a Teflon finish (the one I want to sell is that one). I personally prefer the look of the lightweight all wool better (I am REALLY picky about how stuff looks), but it is a bit warmer.
The Doreen is the prettiest model on; it is not cut as narrow as the Diana, an older style. Pikeur got their start by being a custom made riding wear company, so their tailoring is beautiful on short coats. I personally prefer the Kentucky tail coats (which I do not haveb YET!) as they make Midnight as well as navy which I don’t want. Dover stocks both Diana and Doreen; you can have them send sizes and then pay shipping; it’s better than being stuck with something you THOUGHT would fit but doesn’t. Also, some of the big mobile tack stores that come to shows carry show coats; if you call them ahead of time and ask them to bring some coats for you to try on, they most likely will if they are in stock.
I got my friend a really good deal on a washable Diana at World Cup '05 from a vendor there; she isn’t tall and it fit her like a glove…
I also get almost all my stuff direct from Germany; it takes a while, but I semi-custom order things and they are really great!
