Athleisure: clothing which can be worn in or away from the gym. See also: heaven.
This is perhaps my favorite trend to come about in the last few years. It is the mix of sportswear and street wear. From spin class to the office, if you will. It justifies wearing your sneakers with a blazer and not looking like a complete wacko. Done correctly, it is the ultimate sign of cool.
It’s not your 1980s power suits and sneakers for the walk to the subway. Quite the contrary, it is the blend of luxury fabrics in traditionally athletic silhouettes. A moto puffer jacket with leather detailing. A mesh tuxedo stripe down the side of skinny dress pants. High-class gym shoes and a dress.
