I have typically sought advice (and occasionally received unsolicited advice) from fashion-aware women, most of whom are happy to demonstrate their domain expertise. This has proven to be an efficient strategy that produces good results for relatively low cost. Most of the men I know that dress well rely on a similar strategy; the dearth of men who are savvy at this suggests a somewhat complex signaling game at work.

Take advantage of specialization. It is no different than when individuals solicit advice for me on a matter about which I am perceived as knowledgeable. People enjoy demonstrating their expertise.
