As someone who likes the "flowy" stuff, Personally wish most of the "dress" "skirt" or "coat" like part over the legs were actually apart of the legs.
i pretty much have only have a handful of leg options, as all the "flowy" outfits I like, are attached to the body (and i tend to dislike the upper part its attached to) and the leg stuff either looks weird, or doesnt match the body.
sometimes the "skirt" of an outfit would look fantastic with another upper body, but thats almost never possible.
Then for MOST body armor, a bit goes below the belt, and then overrides any "flowy" leg attachments. (an example, the Lv63 Healer legs, have this bow on them, that looks great, but almost every shirt removes the bow, as the shirt extends below the belt. which by default removes all extra bits of ur legs)
