It's never too early to start thinking of outfit ideas for cooler days, even when the sun is shining. As British weather can't be relied on, having cold-weather pieces at the ready is just a way of life. Plenty of our favourite autumn pieces are trans-seasonal, making them clever staples to invest in at any time. This summer, we're celebrating bright days with brighter outfits, but when days start to cool down, we typically return to back-to-school tailoring, checked prints and a more muted colour palette. Often in autumn, the simplest outfits are the most reliable (especially considering that the weather can dramatically change within hours). We have identified nine basic outfits using a classic capsule—including a trench coat, ankle boots, a cashmere jumper and a heritage blazer—that you can always rely on come autumn and winter.
