Follow the lead of Casual Friday by wearing a button-down and a beautiful pair of trousers, or a knit shirt and denim jeans. Wear a vibrant dress with a professional jacket or a basic top with denim trousers. For a more dressed-up look, wear heels. In general, think comfort first and then add some style. You don't want to wear anything too tight or restrictive, but at the same time, you don't want to be wearing sweats either. Try not to worry about what others are wearing as long as you feel comfortable with yourself and your own style. If you go for a drink after work with friends, you should all be wearing something casual yet still smart enough for an event. This means no trainers, no sweatpants, and definitely no clothes that is inappropriate for the occasion. Drinks after work can be any kind of event: a dinner party, a movie night, etc. The choice is yours! As long as you're having fun, that's what matters most.
