BOGO Sweats

You pick the first sweat without much thought and then have to make a real decision about the second. Matching the one already hanging up, for weight and for colour, gives you a spare instead of a second option. Change something. A heavier loopback, a crew neck where the first one had a hood, or a colour you would never have started with, so the second one earns its own place on the rail instead of covering for the first.
