According to the calendar, autumn is officially here—and I couldn't be happier. This is my favourite season, mainly because of its variety. Some may despair over the British weather, but I love that autumn here involves ever-changing temperatures, oscillating between cooler days and surprising bursts of sunshine and blue skies. Just think of all the outfit opportunities! So with temperatures officially beginning to hit the low-to-mid teens, it's time to truly consider: what do you wear in 15-degree weather?
Fifteen degrees might seem cold to some, but it's actually a pretty nice temperature—still warm enough to walk around in a t-shirt and jeans, but cool enough to justify starting to pull out your light layers. Think the classic trench coat, an oversized blazer or an ultra-soft cardigan. In other words, it's the time for transitional basics to thrive, and the ideal season to examine the state of your wardrobe staples that make up the ultimate capsule wardrobe.
Scroll on to see seven impressive outfits that perfectly demonstrate what to wear in 15-degree weather, as well as everything you need to re-create them.
1. Key Buy: Trench Coat
Style Notes: Trench coats are considered a year-round staple for most fashion types, but they loan themselves particularly well to middle-of-the-road temperatures, too. Often lightweight and resistant to unpredictable weather, they're the perfect addition to any autumn/winter capsule.
