On the Spring 2010 runways we saw a more elegant take on the messy top knot: rather than a messy bun hair is loosely wound around and piled on top of the head for a birds-nest look that's Hitchcock heroine meets modern-day bed hair. Look to Lanvin, Fendi, and YSL for inspiration.
Teasing and hairspray will help create the look. Works well with hair that has some soft waves and texture to it works best on hair with subtle highlights and low lights - raven black or rich brunette colours can be too blokish.
When wearing the top knot make sure you are polished and well presented when wearing casual attire it can make the look sluggish and not as fashion forward. Also when wearing this look you must have dominate eyes or a bright lipstick.
