Beauty dictionary: do the updo

An upcoming special occasion, or just a fun night out, is the perfect opportunity to experiment with an updo. Twists, buns, knots or braids - updos can range from cute to glamorous. Choosing to arrange your long locks or tousled tresses into a simple or elaborate updo hairstyle can be a refreshing transformation. It's the ultimate way to personalize your hairstyle. We take a look at some celebrity styles and how to replicate them.

Diane Kruger's braided chignon

Start with side or center part. Separate and clip the top third of hair. Braid two sections of hair from the bottom half (from one side) and clip. Gather the bottom hair and twist into a bun. Bring the two braids overtop of the bun and pin to the other side. Remove the top hair from the clip. Twist and bring down to pin on top of the bun. Easy!

Emmy Rossum's classy French Twist

Use your hands to smooth the hair to the back of the head. On one side, press the hair flat down against the back of the head and secure with several bobby pins in a vertical line.Then grab the ends of the rest of your hair and begin to wrap the hair in a roll around your thumb, continuing until you've reached the back of the head. Use more pins to secure the twist. For extra volume, tease the root of the hair at the back and crown sections of the hair before styling. Spray all over with strong-hold hairspray.

Eva Longoria's ultra-chic high bun

To get Eva Longoria 's chic bun hairstyle, pull your hair into a high ponytail at the crown of the head and secure with elastic. Twist the entire ponytail and wrap around the base of the ponytail loosely enough that it sits with some bounce and volume. Secure around/beneath the outer edge of the bun with bobby pins. Hairspray the fly-aways.

And voilà! Three great updos for you try out for a great evening look.
