Not so much fashion blogs as they are fashion websites.
This is one that I really like. It has a huge directory of desingers and collections (and they’re all organized by season and year and ahhhh all organized it’s like porn to me) but the bad side is that they catalogue only mayor names like Valentino, Alexander Mcqueen and shit…which are amazing but you know, if you’re using these websites as refs for art like me, it’s not always ideal. Can’t draw your average person doing laundry in a Vivienne Westwood gown. Well I mean, you CAN…but you know what I’m saying (damn it now that sounds like a stupidly good idea..damn. it.)
With that in mind, I’d recommend sites like lookbook, which is a site where people share their outfits and some are incredibly cool. (I have these two people bookmarked because I love their style but I’m sure you can find someone you like)
Here on tumblr, I usually go for Japanese/Korean fashion blogs
