Underwire bras are fantastic for support, particularly for larger chests. But by the end of the day, they can dig or feel suffocating, especially in humid weather when that awkward pool of sweat inevitably develops. For those who have smaller chests, a lightweight, unlined soft bra has enough coverage but also lets skin breathe during the hottest months of the year. Available in lace, florals, and vivid fluorescent accents, these underpinnings are a subtle yet sexy way to be comfortable. For everyday wear, try layering a floral bra like Eberjey’s under a tank or adding a peek of color with Ten’s Yves Klein blue version. And for those special moments, a satin-trimmed bralette by Brulee or Carine Gilson has just as much sex appeal as an over-the-top push-up bra. Click ahead to see these and more.
