Wow the responses on this thread! I'm stunned. Thank you all for your input and support. I won't tag people as such but I will answer the questions I remember:
Wedding is informal and will be an outside affair. Small ceremony and then lovely pub for after. We will have about 15 guests. I don't think a really big fancy dress will suit the occasion and tbh as much as I will feel fantastic I will feel fantastic in any dress that will be special to both me and my husband. We are both so happy to get married.
The maids to measure dress I adore but I do think it is a bit bland for a wedding? I don't know though but I do love it.
I also like the following:

Skirt would need a top. I don't like the Monsoon top it is horrible.
I'm reluctant to buy from vinted without going to try on and buy in person. I'd happily buy second hand though. I do love a bargain if it is right.
I don't really have a set style as you'll notice but I know what I like. I'm the sort of person who goes out looking for the perfect black dress and always buys something so far removed.
