J. Crew Italian Cashmere T-Shirt Sweater, NWT $199

From jcrew.com: Just because it's summer doesn't mean you have to put away the cashmere. - We work with one of the best Italian mills to create ours—it's famously soft, comes in completely custom colors and, if you treat it with love, it will last forever. This T-shirt is just like your favorite, only it's way more luxe. Italian cashmere in a 12-gauge knit. Tubular trim at neck, rolled edge at cuffs and hem. Hand wash. We recommend folding and storing in tissue paper. Import.
