For anyone who was wondering about the authenticity of the clothing in AMC's Mad Men set in the early 1960s, here is a young George Peppard in his role in the 1961 film Breakfast at Tiffany's.
Peppard's not headed for an office in his black and white tweed jacket, tan sweater vest, white shirt with buttondown collar and brown grenadine necktie, but the tie and lapel width authenticate Don Draper's garb. And the tan, white and black tones combine with the fabric textures to give Peppard's clothes plenty of visual interest even though the colors are conservative.
Breakfast at Tiffany's also stars Audrey Hepburn, in my opinion one of the best dressed actresses of all time. Couturier Hubert de Givenchy designed most of her on-camera clothes for decades and she wore them beautifully.
