You know, Annagybe, i've lived in and or near Berkeley, CA for decades now. Berkeley is famous for having a vibrant, large homeless population. I'm a big walker, usually walking 7-10 miles in an average week, and over the years i've been able to observe, and gotten to know, a number of homeless people in Berkeley.
You post made me think about two ladies in particular. One is older, kind of toothless and wrinkled like Mother Theresa, and wears a lot of floral prints in kaftans, robes, belly dancer type pants and a head wrap, all in soft, faded colors. The other i haven't seen in a few years, she was younger and always put together a kind of twenties/retro vibe look, with warm colors. They both always looked very great and definitely unique. I never spoke to the younger lady, but the older lady and i would catch up every now and then and, of course, talk about clothes.
I'm not presuming that the lady you saw on the bus was working her own style as much as the two ladies i've described were. But your comment brought them to mind, as well as Angie's observation that: "Fashion brings us together." Thank you for the thoughtful post. steph
