Actually, my second reaction, the one after "HOLY SHIT!" was "Who's that standing next to Nadine, her mother?" Then I realized it had to be Bettie Ballhaus. Whoops.
Do you think when that blue pullover was new that it probably wasn't a belly shirt? My analytical eye tells me that if Nadine were flat-chested that shirt would be long enough to wear as a dress . . . .
