Well I recently bought a wedding outfit from Vyella (a pink and navy top with matching skirt, all quite flowing and with a pink jacket) and there are some nice outfits at Country Casuals. If you have a department store you can get to that would be a good place too. The accessories are important too, and make it just extra special so once you have your outfit you can be on the lookout. There are some lovely things in dichroic glass now which can pick out the colour of your outfit, I got a lovely heart in John Lewis with matching earrings.
