The 'Jung sisters' Girls' Generation (SNSD)'s Jessica and f(x)'s Krystal showed off their beauty in wedding dresses.

Jewelry brand Stonehenge chose Jessica and Krystal as sister models for 2013. This is the first time the two modeled together as sisters.

With the slogan 'Jewelry that has a pretty line,' Stonehenge had Shin Se Kyung and Lee Min Jung as their models before. This year, they chose Jessica and Krystal to portray a classic and lovely woman image.

The photos that were revealed today were taken with the theme of 'Beautiful Moment Together,' showing the affection or jealousy and envy between sisters.

The photos showed Krystal whispering into Jessica's ears or looking at Jessica with envious and sad eyes.

During the interview, when Jessica was asked what she's worried the most about marrying, she said "I'm most worried about being separated with my sister," tearing up.

The images for this modeling can be seen through Stonehenge's website, Facebook, blog, and many more.
