Stay Cool and Confident

Five bras built for the hottest days on the calendar — strapless, perforated, and open-knit, for whatever heat throws at you.

By Rhonda Shear  ·  Founder, Rhonda Shear Intimates · Updated July 2026

On the hottest days, the details that matter most are perforated or mesh fabric, wire-free construction, and fewer places for a strap to trap heat and sweat. Strapless styles and open-knit textures both help here, in different ways.

There's regular summer, and then there's the kind of heat that makes every fabric choice feel consequential — outdoor weddings, festivals, humid commutes, days that start hot and only get hotter.

Here are five styles built specifically for those days.

Beat the Heat On the hottest, stickiest days, skip padded or heavily lined styles entirely. A thin, wire-free, perforated or seamless bra will feel dramatically cooler than anything with extra layers of foam.

Summer Bra Questions

Perforated or mesh fabric, wire-free construction, and lightweight materials all help air circulate instead of trapping heat. Strapless styles also mean fewer places for sweat to pool along a strap line.

A well-fitted strapless bandeau with underwire support, like Rhonda Shear's Angel Seamless Bandeau, holds its shape through heat and movement better than a poorly fitted one — fit matters more than the humidity outside.

Fabric weight and construction (mesh, perforation, seamless knit) affect breathability far more than color for a bra worn under clothing. Focus on fabric technology first.
