Hiya,
I'm getting married the same day as you!! We're getting married in surrey and have just booked the venue.
Your colours sound lovely...I'm thinking classic romantic with ivories, dark greens with some kind of citrus to brighten things up.
We have 6 bridesmaids and 6 ushers! Crazy times...I'm gonna get the bridesmaids dresses made in Hong Kong (as one lives there and it'll be a tenner a piece!), and we're asking the ushers to hire theirs!
There's a million and one websites...for inspiration I'd look at
pintrest
notonthehighstreet.com
preloved.co.uk (may be abe to find stuff a lot cheaper)
http://www.weddingmagazine.co.uk/
If you've got an android phone i've found 'wedding moodboard' and 'wedding UK' apps really helpful...only scary thing is that they countdown the no of days til the wedding...444 and counting....eeek!!!
Also a tip we're following up...wedding cakes at Waitrose and M&S...save a small fortune! We might be getting 3 tiers of cheese, but not 100% yet...
Good luck xx
Kat xx
