I would like regular clothing for adult and young adult females; I am sick of high heels with everything! I mean who wears heels with underwear or swimwear unless they're in a fashion shoot? Or with shorts & capris? (ok, occasionally I see someone wear heeled sandals with capris, but they're still pretty casual).
Jean-type pants with an alpha bottom and low/no heels would my dream come true. Then people who can recolor, but not mesh, could vary the length to whatever is wanted. Endless possibilities!
Another thing that would be great is more elder clothing that uses the regular adult meshes (that's the only kind I let my elders wear since I found some). There isn't very much of it out there. It gets rid of that horrible shape Maxis seems to think elders should have.
