One thing I love is checking out photo blogs from other parts of the country and seeing how overall styles vary from place to place. Obviously, it depends on the subculture being photographed, but once you start clicking through pic after pic, you'll definitely notice some local trends. For instance, Panda Head, a photo blog charting street style in the Adams-Morgan/Woodley-Park/downtown area of Washington, D.C. (perhaps comparable to...Los Feliz? Lots of singles, artsy types, young government staffers...probably where you want to live if you at all identify as a hipster) reveals that it's waaay more common for people to wear all uber-dark colors, and to use brighter shades color only as an accent.
I think in L.A., these girls would definitely have some springier hues in their tops, or jackets, or something. Blame the East Coast's necessary addiction to big hulking black winter coats, but there's an assumption that one should generally resemble a dark, tree-trunk-like column with only token bright bits. Here in SoCal, though the weather is currently anything but beachy, neon sweaters and jewel-tone dresses are the wintry norm. Thank god--all black makes me and my ultrapale skin look like a morgue refugee!
