Sleeveless tops are the easiest layering piece for fall and this edit rounds up the best business casual workwear styles worth adding to your closet. Starting with work friendly options: a brown and cream gingham pleated V neck tank made for layering under blazers, a burgundy version of the same pleated tank, and a black sleeveless tank top with a relaxed silhouette perfect for the office. For sweater style tanks: a chocolate brown ribbed crew neck sweater tank, a caramel wool blend mock neck tank with a slim flattering fit, and a black V neck sweater vest that works as a cozy layer all season. For something dressier: a champagne satin button down tank with a lightweight silk feel, and an olive green satin tank with a buttery soft double layer, both easy to wear solo or under a blazer. Rounding it out is a beige textured cap sleeve blouse, a brown scallop knit sweater vest, a khaki turtleneck crochet sweater vest, and a dark khaki square neck flowy tank for casual layering. sleevelesstop businesscasual falllayering sweatervest workblouse LTKootd LTKOver40 LTKWorkwear
