Lululemon spent years designing this bra pictured at top specifically for B- and C-cup women who do high-impact sports. Made of a featherweight fabric that won’t chafe delicate skin, it molds to your shape as your body warms it up. A back hook-and-eye closure gives you a gold-medal fit and a removable lining prevents see-through. Lululemon Athletica, nylon-lycra, $79 (34–38B, 32–38C–DD, 32–36DDD); lululemon.com.
Meanwhile, this miracle worker pictured at bottom lets DD -plus women run, jump, Zumba, or even do Cross Fit bounce-free. Double layers of fabric in the cups and wide, cushioned straps provide maximum stability; the adjustable racerback lets you customize the fit for even greater comfort.
