Christina Hendricks was dressed by friend Christian Siriano for her wedding rehearsal dinner this past weekend.

The 48-year-old Mad Men star — who married George Bianchini in New Orleans — stunned in an off-the-shoulder blue and ivory gown by the renowned designer.

Siriano, 38, took to Instagram on Monday to share pH๏τos of the bombshell in the creation, which boasted a mermaid skirt and was covered in a floral pattern.

Per People, the event was a cocktail party held at a home on the Soniat House property.

‘I got to dress my beautiful friend @actuallychristinahendricks on her wedding weekend and WOW it was so magical in New Orleans filled with love and glamour! #sundayglamour,’ Christian wrote in the carousel post.

Christina and George’s nuptials took place at the Napoleon House, where 76 guests gathered to witness the vows.

Mad Men creator Matt Weiner and the actress’ Good Girls costars Mae Whitman and Retta were in attendance.

Retta wrote underneath Christian’s post about the weekend, ‘It was divine. So good to spend time with you fellas. Best brunch laughs!’

Busy Phillips added: ‘The most beautiful ❤️.’

And Shirley Manson, who officiated the wedding, wrote in the comments: ‘Ps. You are a genius.’

Manson, the 57-year-old lead singer of the band Garbage, also shared an image from the festive weekend on social media.

She gushed about Siriano, ‘You are an artist of immense skill and it was a thrill to see you rummage under @actuallychristinahendricks skirt to ensure she shined like the queen she is. Respect to that. Not everyone is willing to go to such lengths.’

For the special dinner, Christina wore her red locks in a side part and face-framing spirals as she pulled the hair back into a low updo.

Christina walked down the aisle in a Katya Katya custom lace gown with a high neck, long sleeves and an A-line skirt.

She wore an old-fashioned veil with a lace cap and two silvery-gray bows.

The Emmy nominee said seeing the dress for the first time made her cry ‘because it was so beautiful.’

Bianchini, a camera operator known for his work on the TV series Peripheral and The Right Stuff, looked handsome in a burgundy and cream plaid suit with a pink ʙuттon down shirt.
