This summer I'm hoping to take up a few athletic hobbies. However, renewing my childhood interest in golf is not difficult from a sartorial perspective; that clothing is well-established. I would even be hard-pressed to think of a way to dress down playing golf. Many people dress better for golf than for their jobs. But I am also interested in an outdoorsy, quick-moving jumping-rolling-running sport known as Parkour. I am further interested in learning a martial art (either Wing Chun or Krav Maga). Provided they don't have any robes or combat suits they want me to wear, I'd like to wear the same I'd be wearing for parkour. I imagine I'd want some loose-fitting, breathable clothing, resistant to wear and tear, but held to standards that we at Lounge are familiar with. I'm imaging something similar to the tennis outfits the Crane boys of Frasier are known to be seen in (but of which I can find no images), but I'd like to hear from you more experienced chappies what my options are. Thanks in advance! EDIT: Not of course that I'm against wearing t-shirts for sports; just wondering how far it can be taken.
