Funnily enough, I was in the What Katie Did boutique for the first time yesterday. You really must pay then a visit, the girls in there are so lovely and helpful! VoH obviously us worth a visit, and you can get Tara Starlet clothes downstairs at the Topshop on Oxford St. There used to be a couple of good vintage shops off the Seven Dials in Covent Garden, but I haven't been up there for a while... Nor have I been to Kingly Court in Carnaby St lately, but there used to be a vintage shop or two there, as well as a fab rockabilly hair salon!
