The texture/resolution work with the dresses is wonky. For instance, there's a blue one and green one that look ok, but then there are others that look all washed out, as if they were ported over from a previous generation game or something. Someone told me it was on purpose by the developers to cut down bog on performance or something, but I don't know if that's true.
And the few unique outfits there are aren't enough to make up for it. Note to Bethesda: When women say they would murder for the perfect wedding dress, we do not mean that literally. And (I would hope) most of wouldn't mean that in character, either. Give us a break here.
How hard would it have been to give you a simple toggle option on the mannequins for 'male' vs. 'female' outfits?

Ulric's outfit looks kinda neat when worn by women. Just throwing that out there for anyone desperate for something new...
