What are the best resources to find the top 100 fashion influencers on twitter?

http://keyhole.co is a tool we have built to track hashtags or any keywords over time in a nice visual dashboard. You can use Keyhole to identify influencers around a topic or hashtag. For example if you search for #fashion or #armani you could find all the top influencers talking about this subject.

I followed my hunch. Entered "top 100 fashion blogs" in Google. This came up: http://www.signature9.com/style-99#rankings It features the top 99 most influential fashion blogs. I scanned the names. The first name that popped up in my head when I saw your question was the Sartorialist. He's on the number 1 spot, so that intuitively makes me think the people who compiled the list know the scene pretty well. Scanning the rest confirmed that.  Most of them are probably also on Twitter and Instagram, given the reach of their blogs. Hope this helps. Another way is to get this if you operate a fashion site is to contact me via DM. I'll put you in touch with my tech guys. They have a platform which actually lets you run social analytics, pair it with CRM and then you can do behavioral targeting. I think this covers both questions you asked, so I'll cross post. As I said, feel free to DM me if you have specific questions.

We have developed a new tool http://www.findtheripple.com, designed to support planning a social media marketing strategy enabling brands to discover and profile their “influence pyramid”: the Twitter community interested in their market sector and its influencers. FindTheRipple was conceived starting from still unmatched concrete marketing and communication needs and its strengths are: (1) combination of a set of criteria (nr of followers or ratio followers/following is not enough) , (2) "reproduction" of the marketer reasoning, choosing those criteria that are really meaningful for a marketer (eg. topic based influencers) and compliant with the social media mechanisms, (3) support to the entire process, from strategy definition to the assessment of the results: providing the influencers list, but also a technology to monitor the results of the influencers engagement strategy. In this period, FindTheRipple is providing for free the TOP50 Fashion Influencers Chart, updated every two weeks.
