The Hart of Dixie actress explained that modest attire makes a woman much more attractive than low-cut tops and skimpy skirts.
"I guess I'm not too crazy about sl*tty dresses. You try something on, and if you feel like a sl*t, you probably look like one," she joked to Lucky.
Bilson went on to reveal that she feels much more comfortable in her pajamas than in a glitzy ballroom gown.
"I just really love being in my pajamas," she declared. "My mother just got me a pair of Miss Piggy pajamas, and I love them."
Bilson launched her own shoe-shopping website ShoeMint last fall, which allows customers to personalise their footwear.
Hart of Dixie airs Mondays at 9/8c on The CW.
