I have never been able to use anything with underwire in it; too irritating for my skin. Target has a sports bra (All in Motion brand) that I really like - not too tight nor too loose - and I also like Puma + Under Armour. I recently tried Puma earlier this year, and I alternate between those and All in Motion. As for regular bras, I only wear them on Sundays mainly - but Hanes makes a nice one that's polyester/spandex blend and I don't feel like it's going to fall off nor be too tight. The material is really soft and there's no underwire, but after many years, they are still holding up.
