When the dress code is business casual but the forecast warns of oppressive heat, the right choice is a blazer made of summer-weight fabric. The material should be lightweight and breathable, with the top candidates being linen, cotton, hemp and lightweight wool.
Ideally, the blazer is also unlined — a style that cuts unnecessary weight and softens the silhouette for a more casual aesthetic. Summer-weight blazers work well with everything from chinos and a tie to jeans and a t-shirt, and with proper preparation for the upcoming heat, you can stay cool without sacrificing style.
