The Bride’s bouquet comes from the old tradition of strong smells warding off evil spirits and bringing good fortune. During the plague in England, people wore pouches of flower petals around their necks because they thought it would stop them from catching the plague, thought to be carried by strong smells.
The throwing of the bouquet is ‘the Bride spreading her good fortune and luck’ – Whoever catches it will be blessed with good luck and be the next to marry.
