I think Jennifer is awfully cute and the Streisand image they chose to replicate is the one from 1963-64, the Streisand of Funny Girl and the famous TV special, My Name Is Barbra.
I went to the original article and on Google Books found this cover of Life from May, 1964, as well as the first page of their article.
I hadn't really thought about it, but up until that point in American popular music the female stars presented on TV were almost always the "All-American Girl" types, with bobbed noses and blonde hair. Nothing against those girls, but Streisand's ethnicity caught my eye when I first saw her. She used to make jokes about her nose, but once I read she didn't get it fixed because a doctor had told her he couldn't guarantee her voice would be the same. So she kept it, and good for her.
Speaking of the sixties...
It was a time when girls and women went nutty for fashion, and we guys really enjoyed watching how far up those hemlines would go! Here's a picture of some folks from Swingin' London. The mod in the middle is quite the natty dresser, like the Kinks song, "A Dedicated Follower of Fashion." ("He flits from shop to shop just like a butterfly..." A gay reference, I believe.) The gals are dressed to be looked at. Stopping traffic, from the picture.
I found these patterns in a thrift store and picked them up for their artwork. I noticed something...they are all made to fit a woman size 14, bust size 36. I assume they came from the same person. The first two are from '67, the last two are from '69, maternity fashions. So what happened in between? Ah, you figured it out, didn't you.
