I got sick of showing up to work with only one post-exercise outfit to change into, discovering too late that my outfit didn't quite come together. (See, e.g., here and here.) Instead of definitively addresing the problem by, say, trying on my work outfit the night before like a rational person, I decided instead to bring one skirt and four different possible tops in my gym bag to change into. I had some ideas of the combinations I thought would work, and figured I could tinker more once I got in front of a mirror in the locker room.
It worked out fine, I think, but the combination I ended up going with was nowhere in my imagination when I threw clothes in my bag.
For those of you who work out in the mornings and put office clothes in your gym bag: how do you put together outfits?
