As recommended by Indeed, it's best to steer clear of logos or graphic tees when dressing for a business casual event or workplace. Given office requirements, you'll also want to avoid clothing items like shorts, crop tops, and flip-flops — really anything that shows a lot of skin. Although Masterclass suggests muted tones (blacks, whites, tans, and grays), look to your colleagues for guidance. If they're wearing color, spice it up yourself with something like these bold purple pants from Banana Republic or even statement earrings from an Etsy small business. After all, bright colors have been linked to boosted moods (via Vogue).
