Bun hairdo seems to be the regenerated hit of runways this week. And we don’t mean traditional tight ballerina knots. Today the stylists go for a loose, messy look.

 “We’re going for something really natural here,” Charles Worthington at Matthew Williamson told WWD. “The hair is natural and feminine like the girls could do it themselves.”

Loose pieces will add romanticism and affability to the image.

“It’s a variation on a Twenties thing,” said Jimmy Paul, who used Bumble and bumble’s Thickening and Surf sprays to create piece-y chignons at Bill Blass.

“I don’t like that perfect structure,” said Orlando Pita, who styled hair for Aveda at Vera Wang. “It’s too put together — it can look unapproachable.” .

In the case of short hair, extensions and chignons will always save the situation.

“It’s a relaxed, sexy look,” Frédéric Fekkai was describing the loose chignons he created at Diane von Furstenberg. “It looks like the girls pinned it up themselves, with pieces flying out at the hairline. It complements the look of the sophisticated clothes.”
