Shimano has short-reach levers (R700) - they're Ultegra grade and priced to match. My hands are small but not tiny - R700s are fine for me.

I haven't ridden Campagnolo since the days of down-tube shifters, but many women here feel that Campy levers are easier on smaller hands.

Placement of the levers on the bars affects reach, as well. Shops probably wouldn't let you try that out since it involves re-wrapping the handlebars, but a good fitter should be able to advise you whether moving the levers or swapping out handlebars would help you enough.
