When you think of updating your wardrobe for summer, a sweater typically isn’t the first item that jumps to mind. That said, a lightweight sweater is an essential for summertime dressing—having something to throw on when the air-conditioning gets to be a bit too strong or when temperatures drop after the sun goes down is always a good idea. The following five styles are our favorite ultra-luxe lightweight cashmere sweaters to throw on when the summer heat lets up a bit.

Its blush of lilac color ensures that it won’t read as being overly heavy when tossed over a relaxed t-shirt.
