Where can I shop for a floor length evening dress in the UK?

My leaver’s ball is in a month or so and I cant really find anywhere that has long evening dresses, my class is big so I’m afraid that by going to high street stores I might end up wearing the same dress as someone else… so basically I’m looking for places other than john lewis,prom dress uk or debenhams that would have a wide range of long formal dresses?prom dress Oh and I live near Edinburgh.. please help I’m in desperate need!

At least worth taking a look.check this place out.school prom no idea about costs , but i pass this shop daily and the dresses are beautiful… and this is a guy speaking!
