Kate Middleton Just Stepped Out In Summer's Hottest Trend—and I Can't Shop the Look Fast Enough

Fun, flirty and a little bit retro, this A-line dress is one you’ll instantly fall in love with thanks to its flattering silhouette and quality construction. It's made of a heat-friendly blend of linen and viscose, with a 100 percent cotton lining to keep you cool and comfortable in the summer months (while preventing any undergarments from peeking through). Plus, the included buckle belt is adjustable, so it'll accentuate your waistline while giving you the perfect fit.

A bit more pin-up than princess (in the best way, that is), this polka dot midi is great for a date night thanks to its curve-hugging fit, sweetheart neckline and sexy front slit that shows a little leg. Available in petite, regular and tall sizing, it also boasts a smocked back panel and adjustable straps to keep everybody (and every body) feeling comfy in it throughout the night. As one buyer writes, "Beautiful! I love the material. It’s not tight on the belly area, but it is tighter around the chest which complements my figure."

Classy enough for work but casual enough for a garden party, this pleated pick is bound to get tons of wear this summer. Complete with a comfortably stretchy waist, the frock is made with Fête Chiffon, which the brand describes as a lightweight, semi-sheer fabric with an ethereal drape. IDK about you, but I could totally see Middleton herself donning this number.

This strapless frock can take you from cocktail parties to beachside brunches thanks to its chic drop-waist design and flowy skirt. Per the brand, it features a side seam zipper closure that makes it easy to slip on, and is made of a mid-weight blend of viscose and polyester that should keep you covered while still remaining breathable. It also has a non-slip silicone neckline that should keep everything perfectly upright and in place, even if you're taking a turn on the dance floor.

This shirtdress from Hobbs London is absolutely giving me Middleton vibes. Between the tailored top (with a point collar and pockets) and the airy, pleated skirt, the style is versatile enough to dress up or down, but will keep you looking polished either way. I love that the tie-waist can be adjusted to cinch in the waistline, and that the long sleeves make it an easy transitional piece you can wear well into fall. Worth the investment? I sure think so.
