If you have to wear a suit all year long, it’s worth investing in one meant specifically for warm weather. Lighten up the fabric, color, and construction to stay comfortable all day.

Speaking of summer suits, you can make your year-round-ish ones work by lightening up the layers. A sleek white tee is the perfect summer layer.

For a more casual office, keep a denim jacket on hand. You can commute to work in a tee to stay cool and put on the jacket once you’re inside.

A striped polo is the perfect way to nail business casual. Not sure what kind of polo shirt feels modern? Start here.

Those polos look good layered with a suit, too. The short sleeves and lighter fabric mean less intense layering—but it still feels like a proper outfit if you take the jacket off.

While the winter might be about outdoor layers, the summer is all about indoor ones. Wear a short-sleeve button-down to the office and throw on a jacket once you get there.

Same goes for sweaters. Wear a T-shirt and pack a knit in your bag.

For suits-only offices, you still have some room for movement. Ditch the tie and go for a printed lightweight shirt instead of a more traditional dress shirt.

Ryan Reynolds flexes the power of a printed shirt. This one still looks put-together with trousers.

Business casual is often open to interpretation. But if your office leans into the casual of business casual, dark chinos and white sneakers are the way to go.

A base for any good outfit: black jeans and a white tee. Put on and remove your jacket at your leisure.

Suits work best in the summer when you still have an outfit once that jacket comes off. A contrast-collar polo is a good way to ensure that.

Think beyond your standard dress shirt for summer. A linen-blend, mandarin-collar shirt is much more aired-out than the norm.
