Isla Fisher Wears See-Through Dress For Courteney Cox's 42nd Birthday Bash

Isla Fisher kinda stole Courteney Cox's thunder when she arrived at her 42nd birthday bash wearing a head-turning maxi dress with a sheer lacy skirt.

The Great Gatsby actress was pretty in her scene-stealing number, which she chose to wear for the girlie lunch at the Giorgio Baldi restaurant in LA.

She paired the frock with 70s-style tan platforms and a matching waist belt.

Birthday girl Courteney, meanwhile, also chose a belted black maxi dress, but opted for a more structured, covered-up version.
