I'm getting married this autumn and I've bought my dress from Etsy, from a UK dressmaker based in Brighton. It's made from antique lace and cost £380. It wasn't made specifically for me, but it fits pretty damn well considering. A little tight at the bust, but I am currently losing weight, so I don't know whether I'll need to have it altered yet or whether it'll be ok. The dressmaker has said she'll make alterations at no extra cost.
I regularly buy clothes online, so had no qualms about buying my wedding dress in the same way. I know not many of my friends feel the same way, but they have said to me that I have an "eye" for knowing what suits me, so they're not surprised I did. It's a complete one off and a million times better suited to me than anything I've seen in bridal shops.
I haven't in fact visited a single bridal shop to buy anything from my wedding, I've sourced it all online - shoes from Not on the High Street, wedding ring from Ebay, etc. Visiting numerous bridal shops with two friends who are also getting married this year made me realise that traditional wedding dresses just aren't for me - they all felt so heavy and cumbersome and I knew I wouldn't be comfortable in them, because I just don't suit the "formal" look.
