Although we’re still in the midst of summer, planning ahead for cooler temperatures and sea-specific outings (yes, there is such a thing!) is certainly front-of-mind. For her rendezvous with the 1851 Trust and the Great Britain SailGP Team in Plymouth, Kate fashioned the below sweater with a pair of white linen, high-waisted shorts and simple accessories.

Much like a number of pieces in Kate’s wardrobe, this sweater is from a designer label. The Lotus Striped Cashmere Sweater by Erdem retails for over $600. But don’t worry. We found similar, affordable styles you can add to your closet right now. Take a look at our picks below.

Women’s Striped Henley Sweater from Fazortev

If you’re looking for something with a bit more room, the Women’s Striped Henley Sweater from Fazortev is perfect. This sweater features a looser fit, with the same navy blue and white striped pattern inspired by Kate’s recent look.

Women’s Long Sleeve Crew Neck Striped Oversized Knitted Pullover Sweater from ZESICA

Ok, we know this selection might not be an exact dupe of Kate Middleton’s designer sweater, but we had to add it here for any curious shoppers. The Women’s Long Sleeve Crew Neck Striped Oversized Knitted Pullover Sweater from ZESICA is ideal for days lounging around the house, or when you need a perfect statement piece for your outfit. We love how cozy this sweater looks — you’ll feel like you’re wrapped up in a blanket all day long.
