`.. be sad and point out that the photo of Emma in leather waistcoat is, of course, a publicity shot from season 4's The 13th Hole. Easy.'

The original poster of the picture, Tom Axtell says:
"As far as I can figure, the outfit was used in an 'Avengers' episode, not just a 'publicity' shot...or part of the 'Emma Peel' line..."

Now Barry says:

The photo of Diana in the leather suit and white sweater is from 1965. I have a photo from the same shoot which is on the cover of Women's Mirror magazine (I remember I did have the original - but it's disappeared) and the date on the magazine is 30th October 1965.
