click on apparel then dirt then a mfr. (like AXO) then protection.
I wear MX knee guards under my jeans everyday (even now
) forget they're there, pretty comfy. the new ones even have dual density foam behind the hard shell cups and more coverage. elbow guards would be the same, easy on/off with stretchy velcro straps. but I bet there's XS gear out there. used to be a couple businesses tailored for women riders only. try searching the net a bit.
another alternative is to purchase your gear and have it customized, say at helimot's or in the city by Johnson Leather.
necessity is the mother of invention!
oops, there are less dirt bike oriented gear in the ads section of most magazines too... Bohn armor co.? I think is one. I been thinking of getting padded shorts, kinda' like bike shorts, for hip and other padding.
oops again, have you been 'round to the local shops? Road Riders has tons of gear. Scuderia in the city. etc. Lots of "leather" shops too :chuci :teeth hee hee
