What I'd like to see more of: frilly skirts and dresses, skirt/tight combination pieces (like the Quimperain's Ruffled Skirt or the Miqo'te loincloth), thigh or knee length skirts in general, winter clothing outfits that aren't limited to Christmas, like earmuffs and mittens.
What I'd like to see less of: swimsuits and swimsuit-like outfits.
