Reflective vest
Try searching for reflective tape, you can find some in various colors. I thought of using some black tape for certain applications. Quick google search comes up w/ stuff like this:

This is example of some of the sew on tape on the clothing, and stick on tape on the bike:

Or if you can't get someone to sew it on, here's some iron on stuff:

I never thought of this, but I see they have some reflective decals (racing, lightning, etc) for helmets, that was pretty cool as far as stuff like that goes...
You can also find leather, and other material, jackets and vest w/ reflective stuff already sewn in that look cool otherwise in daylight, etc. Just to give an idea:

I'm not saying any one of these specific products is what you want, but just giving you some ideas, you could get some sew on, or iron on, tape in black or silver, or whatever color you may find, that would look good fitted to a garment of your choice, or you could find a normal looking jacket or vest that has reflective stripes or piping.
