Capitol Hill Uniform? Another Version

Awhile back, it was noted that there appeared to be a "uniform" on Capitol Hill composed of khaki pants and a blue buttoned down shirt. Since then, I have seen many more folks in this combination. But this particular version is not only eye-catching, but maybe even a little strange. Wonder where this guy works? Chances are he is from New England, or ?...... You could not get away with this sort of thing in the health care environment. There are definite dress codes that must be followed, and they are enforced.

Lobster anyone?
