If you're a fashionista at heart, though, there are subtle ways to give a little nod towards the seasons trends in your wedding guest attire. This season's big colour, for instance, is purple, so this 'Amelia' dress by Monsoon would be just perfect.

The shape will show off your figure without being too revealing, the jewel neckline makes it ideal evening wear, and then there's that lovely rich purple colour - perfect! It's £95, and will need a shawl or other wrap for the church, if you've been invited to the full wedding.
