Annie Flanders, the founder of the original Details magazine — which chronicled downtown New York’s edgy fashion and nightlife scene before being sold to Conde Nast and turning into milquetoast  — was the guest of the evening at last week’s LACMA/Costume Council screening of “Bill Cunningham New York.”

We snapped her on a crap camera at the party afterward, but were tickled to make her acquaintance.

She’s carrying a mallard muff, made by, of all people, Bill Cunningham, who back in the day  had a hat company.

Flanders helped kick-start Cunningham’s career by basically giving him carte blanche to shoot and run anything he wanted in her mag. She’s all over the documentary, too.
