One (1) pair of leggings or any other jegging-esque bottom with an elastic waistband, which will prove reasonably comfortable during both long periods of immobility and short bursts of activity (like getting up to light candles).
One (1) pair of sweatpants with 5 days’ worth of crumbs and stains on them. Wear these whenever you are not wearing the leggings. Sleep in them. Wear them while trying to give yourself a kitchen sink-bath in the dark. Run errands in them. Do everything you can in these sweatpants and save the leggings for times when you need another human being to respond to you in a positive manner, like when hailing a cab. Do not hail a cab in sweatpants.
One (1) pair of water-damaged motorcycle boots. Rain boots are great during the moment of a natural disaster, but are neither warm nor comfortable in the aftermath, which will last at least five days but probably more. (Duck boots are also acceptable.)
Two (2) pairs of socks to be worn on alternating days, but wear both at night because it will be cold.
Two (2) cotton t-shirts to be worn on alternating days, both during the day and to sleep. Do not bother washing the armpits on off-days.
One (1) weather-inappropriate jacket to remind you that you really should invest in a stupid parka from REI or something.
