Oh longsleeved top, how can I use thee? Let me count the ways... for running, for skiing, for wearing to work until holes appear, for biking after that, for chopping wood and for wearing at home until hubby complains.

I think 80 % of my wardrobe in actual use is some kind of workout gear. But while I'm not fussy about sports-specific clothing except bike shorts I am incredibly fussy about using the right thing for the right weather and exertion level, so in any given week I can have a dozen garments floating around in a semi-used state as the temperature shifts minutely..
