How to wear it
Do: go for tousled bedhair, a simple up-do, or 60's sex-kitten voluminous locks; be fashion-forwards, daring, and confident; have fun with it.
Don't: spoil it by wearing cheap costume props. The appeal is in the luxury. This doesn't necessarily mean spending bucketloads, just choosing quality materials and well-crafted accessories.
Do: wear it for a night out, day at the races, and any fun or frivolous activity. A big set of bunny ears is probably not so great for the office.
Don't: wear it with outfits that are too cutesy or girly; it's a fine balance between smoldering sexiness and girly innocence that makes this trend so workable.
