Owner and creator of an apparel line. She is known by her rubber bracelets and collabs with rock/pop musicians. Sells her merch on tours such as Warped Tour, Bamboozle, and Bamboozle Roadshow.

Often referred to as a "scene queen" but I have yet to see her with unnaturally teased hair, neon colored skinny jeans, and a major eyeliner issue.

Former girlfriend of Ryan Ross.

Get the Jac Vanek mug.
A camera loving whore it first became famous for dating the homosexual guitarist for panic at the disco, ryan ross. She continues her reign as most obnoxious scene queen by selling overpriced rubber bracelets that have sayings such as "legit" and "brutal". She states she is still a virgin, but her non existent hymen may disagree. Jac Vanek is currently attempting to take over disneyland as well, by hanging out with Demi Lovato.
Did you see Jac Vanek all up on Alex Deleon at the TAI show last night?
