Re: WHO. Evie is there with Sara (I am p sure!) and wearing thisshe'll step on you if you ask nicely yes, since she doesn't do dresses if she can help it. She's in a good mood overall and is around this bunch a lot so more comfortable here than at most gatherings.
Wei Wuxian is basically just making himself friend of all the final fantasy people if you like it or not. So he brought Lan Zhan with him and was around Gladio and Noct most of the time?? He's a fancy fucker so you get shimmery cape, red and purple to go with. He's never been to a western wedding before and is very :D about the whole thing, there's many congratulations and lots of grins!
