Back in the spring of this year, I spotted some photos of Pippa going to and from the gym in London prior to her wedding to James Matthews. I adored this pullover she was wearing and did some investigating to find out its brand, which now has been ID'd as Peak Performance. I was lucky enough to snag one on sale, and it's an absolute go-to for both working out and lounging around in athleisure wear in case, you know, the urge strikes to go for a run or something. It's made of dry-wick material so it's both warm and cooling, it has a hood, and the best part is a zippy pocket on the back for keys/phone/ID, etc. It's heavy in my casual attire rotation and there are still a few sizes available online!
