The actress praised Valentino creative director Pierpaolo Piccioli for an “unbelievably beautiful show”, which took place at the Chateau de Chantilly, north of Paris.
The eye-catching look comes a year after the star shut down body shamers when she wore a similarly see-through dress by the designer in hot pink.
The actress shared an Instagram post slamming those who felt the need to comment on her breasts, which were visible in the dress.
Showing that she was unfazed by the attacks, the star put her best foot forward in the stunning lilac dress that complemented her pink buzz cut.
