Like some other folks have posted, gear for me is black Lycra bottoms (shorts, Capri, and long lengths), and bright tops- either tanks with built in bra support, or a sports bra under a t- shirt ( usually a race handout). Then there is sport specific gear, but I won't go there. Running shoes are worn strictly for running, and nothing else!
I walk with DH, and we have trails in the woods, so it is usually light weight hiking boots (I like Merrell) and jeans, or chino shorts, and a light long sleeved T. For cooler weather I try for a great sweater rather than a fleece, and sometimes a scarf. When I brought my kids to the park ( they are 21 and 23 now) it was jeans, and t's and comfy sandals or sneakers (like cons or ke ds, but not gear).
