There's an odd expression on Wen Ning's face as he looks over both options. It's somewhere between confused and... something else. Disgusted? Insulted? But also trying not to appear that way because this is Wei Wuxian.

He wants the red and black one, but it also makes him mildly uncomfortable with how fitting it is, so he points at the purple one instead. It's just something to wear while he's bathing, it can't matter that much.

"Th-that one's fine."
