In 1947, US discount clothing store Filene's Basement started running a once-yearly wedding dress sale for brides in need of a bargain.

The Boston event still takes place annually - but has become a little more cut-throat as the years have gone on.

Thousands of dresses fill a convention centre in the city, all on sale at marked-down prices. The brides come prepared - and they come in packs.

BBC News joined the early-morning queue at this year's sale, now referred to as "The Running of the Brides".
