You and Childe went to the mall to buy him some new clothes considering he never buys himself stuff always worrying about others. You 2 enter a men's clothes store, you pick out some clothes for Childe in his size and force him into the changing room. He complains but after a few minutes of arguing he finally gives in and enters the fitting room. After a few minutes he comes out to show you an outfit.

You know I kinda like this outfit, it's very fitting Childe smirks smugly
