What to Wear in 45°F Weather
What to wear in 45°F weather — a simple layering formula, the pieces that work, and how to adjust for men and women.

45°F is cool. The trick isn't a whole new outfit — it's the right layering formula: light knit + a jacket you can remove. Get that ratio right and you're comfortable from the walk out the door to the walk back, without carrying a bag of clothes you never put on.
What 45°F actually feels like
At 45°F it reads as cool, so dress for the real temperature rather than the date on the calendar. Wind and sun shift it a few degrees either way, which is exactly why layers beat a single heavy piece.
The reliable formula here is light knit + a jacket you can remove — enough to stay comfortable, little enough that you're not overheating the moment you're indoors.
The layering formula for 45°F
Base layer: a tee or fine-gauge knit. Mid layer: a light sweater or overshirt. Outer layer: a denim jacket, blazer, or unlined trench.
Bottoms: jeans or chinos. Footwear: sneakers, loafers, or ankle boots. What to skip: heavy insulation you will carry all afternoon.
outfit.so builds each day's outfit from your wardrobe — layered for the actual temperature.
For women and for men
For women: A blazer over a knit lets you shed a layer as the day warms; ankle boots keep it easy.
For men: A denim or harrington jacket over a light knit is the sweet spot at 45°F.
