Fancy dress
I have to say, that I’m not always a fan of cheesy “off the wall” ideas for weddings. When people try to do something cool and edgy it often backfires and makes their guests uncomfortable. The flash mob or the strict dress code for co-ordinated photos just stresses everyone out.

This is genius though, and I wish I’d been around for it. Inviting people to a costume party and then revealing you’re actually getting married is so much fun! No pressure about gifts, or planning, just turning up to have a good time and getting to see your friends tie the knot.
