You know how some bras are just made out of spandex/Lycra and have basically zero support?

I was wearing one of those for things like Morris dancing (think of worse Irish step dancing, basically a lot of hopping up and down), not realizing that it did nothing and was probably much more revealing than I intended.

An actual sports bra isn’t exactly uncomfortable, but it’s definitely not cozy to wear while lounging around the house. It’s much better for jumping though and keeps everything where it belongs.
