Okay, well, maybe not all the time. But in Slasher-prone settings and situations, you never know when you’ll be called upon to run like hell, and proper support could very well save your life.
In fact, you might even want to think about wearing an athletic bikini top as a bra, just in case a swim follows that run.
Sports bras aren’t as flattering, you say? Hell, they’ll make you look athletic, which’ll attract athletic guys, and athletic guys make way better sidekicks when the s#!t goes down.
