Let's say I'm clueless, haven't left my mother's basement for several years, and have no possessions other than my body pillow, Rick and Morty pajamas and gaming PC.

I'd like a complete, comprehensive yet concise list of clothing and equipment I should acquire to start getting /out/ come new years.
From pants and socks to boots and backpacks and bandanas and tents, I want everything of the highest quality.
