My coworker Randy put a lot of effort into a functional IR hoodie,
without success. His results are documented here:

The basic issues, as I recall, were the viewing angle of the LEDs, and
the fact that even the super-bright IR LEDs weren't enough to wash out
the frames that someone's face was in.
I also recall from somewhere, an LED-lined baseball hat, which didn't
work either. No link though.
