Honey, I Shrunk the Speaker

In general, I'm a great fan of Speaker Nancy Pelosi's style. In fact, she was one of the first people to inspire me to write this blog. But the jacket she wore for a speech on the Unemployment Compensation Extension Act was a serious misfire:

The proportion of this collar is so out of whack, it looks a bit like she shrunk after she got dressed, leaving her with a huuuuuge jacket. And in this case, her signature big-round-bead necklace only adds to the effect.

How big is too big? How small is too small? Too narrow, too bright, too whatever? Try this: if the defining characteristic can be described as really _____ then it's probably too _____.
