Dover Street Market in London recently enacted its biannual Tachiagari - named after a Japanese word meaning "beginning". A twice yearly "out with the old, in with the new" ritual, the six-storey shop founded by Comme des Garçons designer Rei Kawakubo, closes its doors for one day allowing designers to restock with the new season's collections. More like a giant art installation than a market, the seasonal changeover gives Dover Street Market - or DSM as it's called by the fash-pack - the chance to introduce a new generation of designers. In recent years it has also begun to set itself apart on the London jewellery scene by introducing up-and-coming and niche fine jewellery designers alongside more established brands like Amedeo and Repossi. DSM's secret to being at the forefront of innovative fine jewellery in London could be its atypical approach, often picking up designers early on in their careers - much like launching Delfina Delettrez back in 2008, just a season after she established her brand.
