Eh, I mean, fit kinda matters more than the specific garments anyway. There's an older man at my office who dresses in a style that looks like a Victorian English professor - hats, tweed and small glasses. It's totally a look that is "older" but he puts it together well and looks good in it.
Cardigans are somewhat fashion-forward and "cool". I have a couple that get compliments from people in streetwear stores (Undercover and John Elliott for any of you fashion nerds).
