Thisis one of my go tos for shows, it’s more of a sports bra but it’s got a nice push up effect and it’s really comfy, plus cute straps.

Here’s a bralette that I really like, it’s super cute with the lace though I don’t wear it to shows due to the lack of support (I’m a 34DD, this would probably have enough support if you’re smaller tho since it has a decent amount of coverage as far as bralettes go).

I’d def give r/ABraThatFits a look thru for better recommendations too based on your size/shape.
