[Wei Wuxian stumbles a little when he hears these questions. Of course they are normal questions to ask but they are still surprising. Perhaps because he has gotten so used to seeing strange clothing since being here that he just never thought to question it.]

They aren't in their undergarments Lan Zhan..different worlds, different years..everyone has different fashion. Apparently as time goes on, people wear less layers.

[Honestly it wouldn't be terrible to get rid of a few layers but it's just not something he has gotten used to the idea of yet. Perhaps he will do a little shopping at some point since there is now a store.]

I think you can wear anything you want now. [He points to a little clothing boutique as they pass by.]

All the stuff in there is the modern clothes that people wear now. You can pick out anything you want to wear.
