Can confirm clipping on the skirt. Actually, it seems more than just that one, it seems to be *basically all* of the skirts D: (I only don't see missing tri's on the Formal, Short Angled, and both the 'long' Talaxian skirts.)
Though I wonder if the Winter Jacket Cropped clipping silliness is related to selecting one of those as an 'OMGBOOBZ' option?
