Dressing and undressing
Dressing HomeDressing 3
John Steed is often shown beginning to undress or finishing dressing in several episodes of the series.

You don't know how to tie a Windsor knot? Just watch The Avengers and John Steed in Death of a Great Dane and The Murder Market.
Steed is dressing in Death of a Great Dane, Dial a Deadly Number and Return of the Cybernauts, undressing in The Cybernauts and fixing the cuff links in You'll Catch Your Death. And of course there is Mr Teddy Bear, when Steed strips down to the underpants, socks and the Fedora.
Steed buttons up the shirt and binds the tie.
Fixing the tie pin and dressing the coat.
This is a unique thing in the Avengers: Steed fixing the cuff links in You'll Catch Your Death.
