I found a littlee website that specialises in vintage items from as early as the 1920's. There is a huge collection of cocktail dresses, jewellry and shoes, that aren't just 'in the style of' but collected from the past 80 years of fashion. The dresses aren't really my style but I love all the leather bag on there. All the workmanship is amazing and they're gorgeous.
They're a bit of a newsence (only one of each style and not cheap either.. plus 80 years can have a negative effect on the quality) but still, they'd be lovely to have!
