Copying my comment from a discussion a while back:

Everything I wear is based around practicality which involves a lot carrying capacity. As someone who's a lot on the move, this is my usual kit:

Jeans, right pocket: Snus
Jeans, left pocket: Bluetooth earbud charging box thingy
Jeans, right back pocket: Boarding pass / ticket Jeans, left back pocket: reserved for trash
Jacket, left front pocket: card holder, in which I also keep receipts
Jacket, left inner pocket: Phone
Jacket, front right pocket: varies. Usually a pack of chewing gum and a pen
Jacket, right inner pocket: Wallet with passport and misc other important stuff
Backpack: Two laptops, a change of clothing, USB battery bank, a bunch of adapters so I can plug in almost anywhere, phone stand, misc access cards, a plastic fork, and a toothbrush. Plenty of room to spare for things I add last minute or pick up along the way.

When I'm only moving locally, it's the same except I don't bring my backpack. And when I'm not flying, I have a small multitool/knife in my right inner jacket pocket instead of my wallet.

Oh, and up until a few hours ago I used to have my sunglasses hanging from a ring that is hanging Frodo-style around my neck. But I realized while I was boarding my plane on my way home that I'd left them in the airport lounge. No time to fetch them, but they weren't particularly expensive.
