Yesterday, walking the streets of San Juan, Puerto Rico, I wore: tank top, shorts, flip-flops, sunglasses and carried our digital camera in my purse.

Today, walking from the bus to work in Washington, DC, I wore: lined wool trousers, sweater, socks, closed-toe shoes, coat, scarf, gloves, hat (not entirely necessary), and carried my blackberry in purse, although not yet turned on because I could not quite face it.
