Check out the Teknic Chicane gloves - it's a leather gauntlet, and they run very small through the palm, but the fingers are long enough for ladies' hands. And I believe they go down to an XS.
Also, Dainese (from what I've heard) run narrow through the palm as well, and are popular with women riders (this from the mouth of the manager of our local Cycle Gear). The Dainese are niiiiiiiice
, high quality gloves. They aren't cheap, but they're well worth the investment (I've got a pair on my wishlist).
However, if you want to order/wait for gloves, I'd highly recommend any of the Alpinestars Stella gloves (and I THINK their men's gloves go down as small as an XS... I've got a pair of men's gloves, some little lightweight meshies for summer riding, which I love).
Joe Rocket Pheonix 1.0 (mesh, Men's M)
Joe Rocket Phoenix 2.0 (mesh, Ladies' L)
Joe Rocket Sonic (leather gauntlet, Ladies L)
Teknic Chicane (leather gauntlet, Men's S)
Alpinestars SMX6 (soft meshie, Men's M)
(and another pair of winter leather gloves, the name of which escapes me!!)
And I just ordered a pair of the Joe Rocket ladies' Heartbreaker gloves (to go with my new jacket - the Cleo 2.0
) in white/purple. I should have them by the end of the week, so I'll let ya'll know how I like them.
