There's a few things in the clothing stores around Traverse Town. I haven't looked at Twilight Town much, but there should be more there since it's so much bigger.

[Considering she might be the "girliest" looking of all the girls currently in the worlds, Ziva could probably assume Asami knows what she's talking about. Even with the goggles pushed up to her hairline.]

What do you need them for, exactly?
