I'm not sure if it's the height exactly, but I've definitely noticed that the angle of skirts on Roegadyn is tilted forward compared to other races, so they sit awkwardly forward at the front and the hem doesn't hang down evenly.
(The princess dress is huge and too high on the waist for everyone - I suspect it was modelled for Lalafell first. This was a screenshot I'd taken a while back of it on my Midlander and a photoshopped attempt to make it look better.)
