I'm trying to get more "fashionable" of late, which ultimately means I'm just dressing a bit smarter. There's no point trying to follow a fashion if it's clearly not you. Try and discover what clothes you want to wear and what overall kind of style you want. Is it smart, hipster, goth, prep, country bumpkin? And then take it from there. Though that all being said, I quite like askmen.com and dappered.com. But you can get some good ideas just from the pictures from the mainstream fashion places like zara and H&M.
Remember that the fashion blogs and the like are heavily sponsored and suggest ridiculously expensive products. Good for getting ideas of styles, but not for actual product recommendations.
