While he may be currently single, Jersey Shore‘s Vinny Guadagnino knows what he wants in a woman.

“I like girls to be natural when it comes to being sexy,” Guadagnino told PEOPLE at the recent launch of his new T-shirt line at Greenhouse in New York City. “It’s not about how much skin she is showing, but whether or not she is showing off the right parts of her body to keep me interested.”

So what about a woman catches Guadagnino’s eye in particular? “A bare shoulder is pretty sexy,” he said, “and just enough to keep me interested.”

But when it comes to a relationship, Guadagnino, who once called Nicole "Snooki" Polizzi "beautiful," expects more than just a physical attraction. “She has to have a personality that vibes with mine or it won’t last,” he said.

While it’s good to know what one wants in a woman, don’t expect to see Guadagnino – who often tags along with roommates Mike “The Situation” Sorrentino and Paul “DJ Pauly D” DelVecchio on nights out to pick up women – to get too attached to anyone in particular when he heads back to Seaside Heights, N.J., for season 3 of Jersey Shore, which premieres Thursday (10 p.m. ET) on MTV.

“I’m only 23,” Guadagnino said. “I’m doing what I am supposed to be doing. I’m absolutely loving it.”
