Here's a really good buy: the linen sweater from J. Crew, on sale now on their website for $39.99!
I bought it last year in Sandstone and this year in the lively Soft Fuscia, shown.
It's perfect for air-conditioned interiors, and the deep V neck is flattering to everyone.
Only drawback is "dry clean only" but I'm about to try handwashing one, as I do with my linen blouses.
