I got married in the Ghost version two weeks ago! I got it from ebay for £50. There's a sage green one in your size at the moment. If you've got time, keep looking as they do come up. I'd sell you mine but I love it too much to part with it! It irons like a dream ( on the reverse side)
I felt brilliant in it, and got so many compliments. It's such a classic yet glamorous style ( the Nobody's Child one is exactly the same)
For flowers I made a hand tied bouquet from roses and lavender from the garden plus some supermarket flowers. A real mixture looks more casual. I bought double sided ribbon and pearl topped pins from Amazon.
I wore gold sandals from Monsoon and had a off white clutch bag from ebay. I looked bridal but without it being too much, and the whole outfit was £120!
