Christina Hendricks is all business in a floral blazer as she arrives for celeb-packed Day of Indulgence party

 Her most famous role was as office manager-turned-director of agency operations Joan Holloway in Mad Men.

So it comes as no surprise that Christina Hendricks was all business on her latest outing.

The 46-year-old actress was seen rocking a floral blazer as she arrived for the star-studded Day of Indulgence party thrown by Jennifer Klein in Brentwood, California on Sunday afternoon.

She commanded attention in the business casual look featuring a white T-shirt, skinny black jeans  an intricately weaved sandals.

Christina completed the look with black accessories including wayfarer shades, designer bag, and polka dot protective face mask.

Her signature fiery red locks were worn down in waves which blew in the wind. 

The star-studded affair was held at the Brentwood home of film producer Jennifer Klein. 

The women's-only party, which is thrown annually by producer Jennifer Klein, is a regular retreat for the A-listers and a chance for them to take in some pleasurable pampering.

The ultra-wealthy actresses and entertainers each are given a variety of expensive swag for free, and several stars were spotted pushing out massive Samsonite suitcases, which InStyle reported could be filled with as much as 80lbs of goodies. 

The event seems to be quite the afternoon of fun as guests are treated to food and beverages as different parts of the property make for different experiences including a free outdoor swag bazaar in the backyard and pop-up boutiques in rooms that include a mix of shopping and gifting. 

The celebrities can then end the day relaxing by the pool where there are spa treatments available.  

Jennifer Lopez, Olivia Rodrigo, Christina Hendricks and Alexandra Daddario, were just a few of the major celebrities seen at the event.  

This is the 23rd year for the unmissable event, which continued last year despite the ongoing coronavirus pandemic.

At that event, attendance was limited compared to previous years, and guests were required to be masked and to social distance at all times.

It's unclear if the guests list was curtailed again for 2021, though several guests were still seen wearing masks at various times. 

It's considerably safer this year even with many people going unmasked, as many of the attendees are fully vaccinated against Covid-19. 

JLo, 52, certainly had all eyes on her as she arrived with her 13-year-old daughter Emme.

The Out Of Sight star rocked a playful summery ensemble featuring a skimpy pale lavender tube top that put the spotlight on her washboard abs, which she proudly displayed.
