This bride has a very large fancy bun with many rolls and a tiara.
A very formal look and hairstyle to go with a simple satin strapless gown that is form fitting down to about mid thigh where it blossoms into ruffles.
If there is enough length, sections can be folded into shape and pinned and then rolls created. For shorter locks, a ready made hair piece made to match the color would be the answer.
