Well, after a lot of web-research and embarrassing several salesmen by having to jiggle and adjust (they soon understood the particular challenge that ladies face)
I think that I have a winner!
I have found that there are 2 front runners: Knox & Dainese. Knox are a UK based company who make some highly recommended and safe gear. Although the Cross shirt 1 (2005) fits very well - the chest plate is heavy duty foam and moulds to your shape - I have opted for integral body armour that has a moulded more solid chest plate in it (if I'm going for good protection, I may as well go full hog!). Dainese make some great body armour that has a shaped chest plate that can accommodate (well enough, considering some of the very badly fitting stuff that there is on offer) shapely feminine curves. The draw back is that the armour comes at a pretty hefty price!
I have made a compromise and have ordered some Dainese-like gear that utelises the same design but offers it at a much more affordable price (all CE approved though, so no short cuts there!).
A friend is very happy with hers, so I happily await my package in the mail!!
Thank you all for your advice.
If you don't have bugs in your teeth, you haven't been grinning enough!
