That's where Style Nibble comes in. Founded by Heather Bird and Nigel Whiteoak, both previously with online site ShoeDazzle.com, Style Nibble aims to provide you with a manageable number of fashion recommendations to suit you.
The site works using a combination of automated matching based on previously revealed preference, and selection by a real-life stylist. The results are rather good.
Once you've finished the questionnaire you get assigned to a stylist, who has their own facebook page, twitter account and email, where you can ask them questions. I'm with Olivia.
The site is still very new, and there are some annoyances, such as having to repeatedly log in, even when clicking through from a recommendation email, but even so I think this fills a much-needed gap in the market. Viva la Style Nibble!
