Models took a walk on the wild side at the Christian Siriano Spring 2011 fashion show, where hair and makeup evoked a romantic, nomadic feel that complemented the designer's use of multicultural prints.

Uber-stylist Antoinette Beenders, working with Aveda, created a "tribal bun" with an "Afro-like texture" that elongated models' upper bodies, giving them a "giraffe neck". Here's how she did the sexy updo:

• Pull the top section of hair--from hairline to crown--and clip it out of the way. Comb remaining hair back and into a tight, high ponytail. Spray with Aveda Control Force Firm Hold Hair Spray.

• Spray shine spray directly onto the bristles of a kabuki brush, then "paint" the sides of hair with the brush to create a high-shine finish.

• Take the ponytail and braid it. Twist the braid into a bun and secure to the head with bobby pins. Spray with hairspray to hold in place.

• Remove the clip from the front section of hair and comb back. Working with small portions of hair, use a micro-crimping iron to add texture from the crown to the ends. Brush through hair with a paddle brush to soften the crimp.

• Gently pull the hair over the bun and secure at the base with hair pins. Spray with hairspray, then pull a few pieces of hair out of the bun with your fingers to create extra texture. Spray one more time with hairspray to lock everything in place.
