Strappy tops - does she need to wear a bra? If so are we talking fuller figure? Solid supporting bras have wide straps which need covering up.
While I try to keep out of her underwear I do have a much later scene where she is wearing a sports bra under her super hero costume (because, like sport, I assume super heroing requires some practical support).
There is a minor character who makes an offensive remark that only makes sense if she does need to wear a bra...
And moving away from all the practical details to a couple of characterisation question.
So they are people who like each other - they've got to know each other for a while - and since the whole dressing up thing is unexpected from what you've said, that means neither of them is a dressy person.
Why does he suddenly dress up? Why is it not just cleanest T-shirt and jeans?
Why does she think "ooh dearie me, I must dress up too" NOT "he's dressed up, I didn't think he was like that at all, mm, going off him now".
The idea is, she thinks he's gone to a lot of trouble for her (she didn't even know he owned a shirt with a collar, apart from his school uniform shirts). She's thinking he'll think she's not serious about the whole more-than-friends thing.
