Spring in the city always presents a few challenges. Getting dressed is tricky when the weather is sunny and 60 degrees one day and a frigid 40 the next. My beauty routine is also thrown into a loop when my go-to thick face moisturizers suddenly become too heavy for my sensitive skin. So what's a shopping editor to do but turn to the coolest girls I know for inspiration on elevating my spring wardrobe and beauty cabinet?

Right now, all of my favorite fashion insiders (and my fellow Marie Claire editors) are favoring elevated, easy-going styles these days. One trip into the office has proven that Adidas sneakers are the trendiest shoes this season, and that Hoka running trainers are best for casual athleisure outfits that still feel cool. Breezy linen trousers and track pants are also coming into favor as the weather warms, as are retro-feeling graphic tees.

On the beauty front, I'm seeing that effortless vibe carry over with natural, skin-loving products. Think: a foundation with a your-skin-but-better finish, viral Japanese and Korean skincare heroes, and a radiance-boosting toner Beauty Director Hannah Baxter includes in her morning routine. And yes, her skin really is that flawless in real life.

Ahead, you'll find those picks I'm shopping, including the must-have spring sneaker styles, transitional wardrobe pieces, hair holy grails, and more. Keep scrolling for all of my must-haves.
