The rumor is the one day, Edie was out swimming. She in the local pool, and it was a hot day in the middle of summer in Southampton, at a time when the pool would have been filled with young people. This would have been around the time she was a debutante, so she looked like this:
I find that this is the kind of picture I look at and think “no juice cleanse in the world would make me look quite like that.”
She was pretty modest about, at least when she was young. Of herself, she wrote in her diary that “”I can’t really tell you if I am pretty or what kind of girl I am but … I have long hair, blonde, getting darker, deep blue eyes, a pug nose and a rather decided mouth. I am by no means fat, but I have a good body and big feet.” However, Joe Davis, a cousin of the Beales, wrote that “she was the family beauty, surpassing even the dark charm of Jacqueline [Bouvier, later Kennedy, later Onassis]“.
So, other people could tell her what kind of girl she was.
In any event, she was rumored to have dove into the pool – and her swimsuit slipped right off. Some girls would have been mortified, but Edie Beale got out of the pool, stark naked, walked up to the most handsome boy there and asked him if he had a towel.
