If your bra straps come with a j-hook feature, take advantage of it! Especially if you have sloping shoulders, the j-hook will quickly become your new best friend. This small piece of hardware is easy to miss if you don’t know it’s there but once you start using it, you will be hooked (no pun intended!). When the j-hook is clasped, traditional straps instantly turn into a racerback. They sit snug along the shoulders and back and won’t slip or slide.

There are many things to love about racerback bras from the flattering lines they create along the back and shoulders to their ability to disappear under tank tops with tricky necklines. And one more thing that racerbacks consistently deliver? Straps that fit so securely, they never slip and slide.
