Do push up bathing suits look ugly?

I’m really self conscious about my body. I’ve been trying to workout but my work/life schedule doesn’t always allow it even if I wake up early there’s always something to do.

Anyway, I have small boobs and feel like they are nonexistent in bathing suits. I really want to have a fun trip and not be so self conscious I can’t enjoy. I was thinking about getting a push up bathing suit so help out my confidence.

Do they look ugly? Can you tell they are push up? Will people judge me or will I be less attractive? Idk help
