Hot, humid weather is gripping much of the nation. To maintain relative comfort during summer outings, pick the lightest-weight fabrics and colors, Stitch Fix says. Think shorts, light skirts and sleeveless tops in whites and pastels, and fabrics that breathe such as cotton, linen and rayon. “Take a take a pass on polyester (not known for its breathability) and silk,” the story says, and opt for loose-fitting clothes to keep those sweat stains away. Seersucker and eyelet weaves are solid choices for summer.
