I think you good do a lot to help make gear better for both genders by simply not having so many robes and capes and gowns. And bring in more shorter options.

dalmaticas shirts or jackets sort of thing for a healer body instead of the full length robes and gown they tend to go with would help a lot. You could feminise that jacket with dyes or accompany it with a skirt and thighboots if you chose. Or masculine it up with dyes and a pair of slacks.

Similar things could be done for a lot of dps and tank jobs. Again theres so many gowns and robes and capes out there but not much else. Theres a lot of sets out there I'd actual like if they didn't have giant full length capes every single time.
