The old saying goes that March "comes in like a lion and goes out like a lamb". Here in Portland, the lion and lamb days alternate so that it's no telling what the next day's weather will bring. When it isn't winter anymore, but definitely not yet spring, what do you wear?
March is a good time to put your black wool turtleneck and dark, heavy coat into storage and turn to brighter colors. Get out your grass green mohair cardigan and cotton sundresses. Do you have a light, off-white cashmere coat? Maybe a blue linen coat? If you do, move them to the front of the closet. (If you don't, we can fix you up at the Xtabay.)
Now that you've brightened up the color of your wardrobe, think about how to wear a mix of your winter and summer clothes for March's unpredictable weather. For instance, you can toss a lilac cashmere cardigan over your tulip-print 1950s cotton dress and wear it with boots and a spring coat. Later, when spring hits full on, ditch the boots for sandals.
You can also lighten up your clothes this time of year by playing around with accessories. Try switching nude fishnets for tights or wearing chiffon scarves instead of wool scarves. Dump everything out of the giant leather bag you've carried all winter (face it, it's probably time you cleaned it out anyway) and carry a smaller, brightly-colored bag. Put away the bottle of heavy perfume you might have been wearing and try a spritz of hyacinth-scented Guerlain Chamade.
Before too long it will be April...
