This is a nice little lingerie dress by Leigh. It’s a gift for members of the teleporthub.com group, which is a tiny L$10 to join.
It’s sized to fit Lara, Venus, Freya, Isis, Hourglass, Physique, Legacy, Curvy, and Fine, and comes with a four color HUD that also offers some glow and transparency effects. The five standard mesh sizes are also included for classic avatars.
