On April 29 2011, nearly 3 billion people tuned in to watch a girl from Bucklebury marry a prince born to Buckingham.

"Few people were wearing them, but now they've suddenly taken off," says headpiece designer Tia Mazza. Anticipating the post-wedding clamor for crowns, Lindsie Jones, owner of Haute Bride, created a successful new line of chic tiaras. "They've almost sold out," she says.
