He wasn’t a big talker, but he had a certain, extraordinary charisma that gave you a kind of permission and license to be freer than I’d even been able to be," said Bottomly.

[11] Her time as a Factory star illuminated her beauty, and seemed to draw people to her with a kind of ethereal grace and allure.

In her book, Woronov recalled that "Velvet was a slob; a girl slob, messy but sexy like underwear and perfume ... was a society girl from Boston hoping to follow in Edie Sedgwick's footsteps, footsteps that seemed to lead straight to the rubber room so far as I could see, but that was her problem; I was more than willing to be the first step in putting her there.

Bottomly became involved with Velvet Underground members Lou Reed and John Cale, causing more conflict in the group, which was already disintegrating.

[15] Bottomly and Croland accompanied Warhol to parties and gallery openings, bringing attention to their bold style.
