Wow, lots of links.
That shearling is lovely shop - I would be concerned about it not closing up though, and getting cold.
I like the Barbours too. Think I may look for that and a shearling / sheepskin coat next winter (if this one ever ends).
I'm not an expert on these things, but I also think you should be able to sell your Gina shoes, Shop. They look lovely and not too 'wedding-y'. An alternative to ebay could be one of those shops that sells things for you (a dress agency?). I sold my wedding shoes through one, they do take a cut but I don't think I would have sold them for as much through ebay. They were a pair of white heels by opening ceremony, so maybe less sellable on ebay than Gina shoes.
I just bought a metallic bag in the charity shop, £12.50 and it is a Michael Kors bag...may be my best bargain. Had been looking for a metallic bag for a while and had considered:
peony&moore
Sara Berman
Amber, I saw this on the peony and moore website and thought of your Sophie Hulme bag, in colour at least.
Also, your wishlist sent me looking at the Jemima Vine website, love the shoes.
I'd never heard of tanzanite. I am also not so keen on the ring novice but I do prefer less classic jewellery so it is not really my style. I feel like I have seen similar rings, maybe you could get one with a tougher stone?
