What are some good European stores such as agatha ruiz de la prada?

I am a teenager that lives in the states and loves fashion. I am getting really interested but Europe's fashion's scene. Can you please give me some links that would lead me to some cute little boutiques or just nice brands. Agatha ruiz de la prada is a wonderful example of what I am looking for! Thanks!|||Well I live in united kingdom but most of the shop are getting American like Ralph Lauren, Hollister, amercrombie and Fitch etc.
