If you think the Fifth Doctor’s clothes aren’t wearable on the streets, you would be right and wrong. Peter Davidson’s character didn’t wear a costume…he wore a uniform. This is what cricket players wore on the field. They did not, however, wear a stalk of celery.

In fact, now that I think about it, a stalk or celery, or better yet, a celery-shaped pin, is a cool way to pay homage to the Fifth Doctor.

3: Tie – no tie. The Fifth Doctor does not think bow ties are cool.
