I found these sports bras recommended on Reddit and wowie wow, they are great! I ordered ones recommended for high impact and they truly keep everything in one spot. When I first unpacked them I was certain I wouldn't be able to get it on but once it is on nothing is moving. I live in really hot and humid temperatures for most of the year and having the bra like hook at the back does help peeling it offonce finished a run or a boot camp session. Also, thank the designer gods that someone figured out how to include bra padding that DOESN'T MOVE! There is no shifting while running, nothing missing when coming out of the wash and no weird bulge from a misshapen cup! I will say though, not so comfortable for just lounging around.
These will be my new go-to.
