"I swore off cardigans after owning so many bad ones in high school and university — when everyone would wear them over their spaghetti-strap tank top – and it's a look I don't care to revisit. That being said, I love the idea of tucking a buttoned-up cardigan into high-waisted jeans — as you would a blouse — and I'm obsessed with the detailing and delicate quality of this Sézane Garance Jumper (£90). It's sold out on the website, so I'll be making a visit to the store in Notting Hill and I signed up to be alerted the minute it comes back in stock." – SP
