Different versions of a bun are examples of elegant updos that some celebrities have worn for special occasions. The chignon and the French twist are also classically elegant updos.
Jennifer Lopez wore an example of an elegant bun updo. The stylist created a soft bun high on her crown and swept the front to each side. Penelope Cruz wore a similar style but with the bun lower on her head and with backcombing in her crown.
A chignon is a type of bun but worn at the nape of the neck. It's possible to create different versions of the chignon, such as a smooth twist or with backcombing at the crown. Another option is a chignon created out of big waves with braiding on the sides. Some women also add accessories to the chignon to match their gowns.
Another version of a chic bun is one that's swept to the side. Stylists often combine this look with waves in the front. The bun typically projects from behind one ear. Hair accessories are common with this updo as well.
The French twist is another classic updo. Stylists create this look by sweeping all the hair over to one side and pinning it in place. They then roll the hair up into a twist. Another, more romantic version starts the same way but gets rolled down instead of up, leaving the hair at the bottom to flow loosely.
