I wear colorful men’s clothes. Fun designs on things like short sleeve button shirts in the summer (Hawaiian shirts and similar things), fun sweaters in the winter.

Even my office wear usually has a splash of personality, with the amount of subtlety appropriate for the setting: suits or jackets with interesting textures and weave patterns, neckties with interesting designs, a bright color on my socks. Some settings allow for a bit more expression, and other choices can be more adventurous if you prefer, including intentionally contrasting choices in glasses, watches, shoes, other accessories. Even a pair of headphones can be a fashion accessory, although it is true that women seem to be able to pull that off better.
