It's been an uncommonly cool day here in the DC area, with a high in the low fifties (Fahrenheit) and overcast skies. A kind of day where you'd want to wrap yourself in something warm and take a nap.
I rely on blankets, but this cocoon wrap from Italy's Loro Piana in cashmere/silk would be a luxe ($790.00!) option, but as SWAV notes, "too rich for my blood."
I particularly like the free form style with open sleeves. Found through Bergdorf Goodman.
