Not exactly tuxedo, but I'm EDCing a lot in my business sport coat quite inconspicuously. Including the cut off steel flask with USB self solar charging power bank, AC adapter, USB cable, disposable rain poncho, pepper spray, shocker, water filter, lighter, 256Gb total of various type and format data storage, set of credit, id, business, RFID/NFC access cards, 2 sterile scalpel blades, some pills, safety pins, sewing needles with plenty of #8 nylon thread, and a microfiber cloth. (even more stuff is on my belt, on the neck, and in the pants pockets). The secret is in the organizing this stuff in flat bundles distributing the bulk evenly in the pockets.
