Victoria's Secret model Joy Carrigan leaves little to the imagination in a skimpy green dress.

Victoria's Secret model Joy Corrigan gets ready for a party, apparently without her underwear.

She wore a tiny green mini dress on a night out in Mexico while on a fashion shoot for sports brand Alo.

Joy turned 27 while she was there.

She went out with her sister Gina to celebrate at a restaurant in Cabo San Lucas.

At one point, Gina came to her aid when a strap was in dire need of adjustment.

But fans scoffed and wondered if she was wearing anything underneath.

Earlier this month, Joy revealed her laid back attitude to show off her body.

She confessed, "I love being sexy and I love showing skin because I work out a lot to get the body that I have.

"I've always had a very free spirit about it."
