I bought one from Promotion.They do a range of windsurfing specific wetsuits with loose upper arms and upper body and dryskin. They offer good customer service including exchange if the fit isn't right (even if you have worn the wetsuit!) and with US exchange rates the price is good. You won't have to wait long either - I think mine arrived within a week or two from when I ordered it.

I have now tried out my (ladies 5/3) wetsuit in wintry conditions. It is so warm and cosy and takes the pain out of falling in. People say the water has become very cold but I haven't noticed. The wetsuit is very comfy and doesn't feel tight at all. It is loose around the shoulders so even lifting the arms above the head for waterstarting isn't a strain, and it is so bouyant I can almost float standing up! The dryskin stops windchill/evaporation chill when out of the water so I don't have to change into dry clothes in the freezing carpark and can drive home in my wetsuit. I arrive home warmer than I often do in the summer!
People keep asking me what brand it is because I look so warm and comfy - ProMotion.
