It's not just girlie kit although Corrine Dennis specialised in that field. Most of the stuff is more roadie than mountain bike, but it's good quality and hand made, as a pair of shorts I bought from this company were a good set of summer touring shorts and they lasted for ages. A bit light for the tumbles and brambles of full on riding, but good for the purpose they were designed for.
As far as I remember the company is near York, and does mail order and sells to some bike shops in the area.
