I haven't seen the flaps (aka "skirts") on the formal dresses mentioned yet. Just me? Attempting to edit the formal costumes at all often produces a bunch of random changes when you click the Formal tab, but I'm not sure if that's a new glitch or an old one.
Also, one of my characters who is very short gets randomly covered in deep shadows at the tailor, and the only way to turn the "lights" back on is to change something. Certain combinations always trigger the shadow, and it's dark enough to make it impossible to see the outcome of smaller changes.
Finally, am I mistaken, or did the TOS Mirrorverse Sash used to have 2 color options? I only have one for the belt portion now, while the loose part is stuck on the default color.
I'm also missing all these previously mentioned bits:
TOS Mirrorverse earrings (not sure about the Bajoran ones)
Trill skin patterns (excluding face)
Body parts turning invisible if left uncovered (excluding face)
