For some DIY inspiration for next season you could just watch some old films and hunt out ancient family photographs for pictures of your father, grandfather et al. If you can find the time for hobbies then manly pursuits such as mountaineering, fishing and relaxing in a log cabin should help you channel the red-blooded vibe!
What this means in practical terms is that updating your look this season will be a fairly simple affair. Look at what's already in your wardrobe and try to work with your basics. Charity shops will be a good source of classics; the more suburban and remote the charity shop, the better your chances of finding threads worthy of an honorable gent.
