Michelle Pfeiffer is proving that she's a timeless beauty in back-to-back appearances.

On Tuesday night, Pfeiffer, 67, attended the Yves Saint Laurent Womenswear show during Paris Fashion Week. The actress was in head-to-toe YSL and wore a black blazer with matching slacks. She rolled her sleeves up to about her elbows and wore green heels with a dramatic pointed toe.

Pfeiffer tied the look together with gold bangles and a sheer shirt underneath.

The "Scarface" icon shared photos to Instagram, and she was instantly flooded with praise. "Absolutely stunning show! 🔥 Thank you for having me, @ysl @anthonyvaccarello 🤍," Pfeiffer captioned her post.
