Ever since spying January Jones’ headband-adorned updo at the Golden Globe Awards, I’ve been in search of a hair band of my own. This Metallic Whip-Snake Headband from J. Crew ($18.50; www.jcrew.com) fits the bill. The textured leather is subtle enough to wear day and night, but more interesting than basic black or tortoise shell. Best of all, it makes my messy chignons look instant neat and chic.
