Hi
I ordered the
Leather Look Jacket from them. If you scroll to the (very) bottom of the page, there's a Sizing Chart link that may help. It has both imperial and metric.
Hopefully my old pic uploaded. Anyway, their sizing chart said I was on the line between medium and large, because I am muscular, I should have ordered a large since the medium is a little snug in the shoulders and I cannot do it up. Even so, I'm still happy with it because it helps minimize the size of my arms and broad shoulders.
The jacket did fit better than most women's medium jackets. But I don't order from them because "they're designed to fit a guy's body". I only really order from them because I like some of the outfits, and some of the designs/contours seem to help slender and feminize certain areas.
To be honest, I get most of my clothes from regular outlets like WarehouseOne, La Vie En Rose Aqua, La Senza, WalMart, and the like. Generally, a men's medium is roughly a women's large, but not always. When I'm too self-conscious to try on the clothes in store, I'll buy a test piece as a "gift for a friend/girlfriend" to try on at home. If it doesn't fit, it's easy to exchange for the right size.
After resurfing their site on sizing, I discovered they have quite a few articles: Lifestyle & Empowerment, Sizing, MtF Voice Lessons, Coming Out, Style & Fashion Advice...

Anyway, not sure it that helps but that's my only experience with them so far.
