Brown Eyed Girls' Gain discreetly showed off her sexiness.

Gain recently filmed a underwear photo shoot with casual innerwear brand 'Yes', revealing her voluminous body.

In the photo shoot, Gain showed her feminine side, unlike the strong and charismatic image she has been showing on stage.

Gain, as the original of disappearing-pants fashion, wore shorts to reveal her leg line. On top of this, she wore a pink and yellow bra.

One representative said, "We wanted to express the lovely yet sophisticated image that only Yes has through Gain."
