Raincoat Styles
Although the raincoat has become so familiar that it seems like a uniform, in fact Columbo finds new and innovative ways to wear his signature garment with variety, flair and personal touch.

In A Case Of Immunity Columbo pioneers the “Raincoat and Tuxedo Look,” which is displayed again through much of No Time To Die. Dashing.

Confronting Col. Rumford (Patrick McGoohan) in By Dawn’s Early Light, Columbo wears the coat in a casual, almost “off the shoulder” fashion, revealing his sleeveless white undershirt beneath to complete the ensemble. Stunning.

A bit earlier in the episode, Columbo wears the raincoat into the bathroom to perform his morning ablutions – essentially using the raincoat as a bathrobe. Stylish and practical.
When Columbo responds to a murder scene late at night, he sometimes throws on the raincoat in lieu of a shirt, over his bare chest or pajama tops.

Perhaps this display of Columbo’s white chest-hair is what drives Faye Dunaway to such a frenzy of seduction.

On the cover of this antique paperback, we see the coat fully buttoned-up. Rarely seen.
Fascinating stuff!
