It from their Zsa Zsa Zsu 2021 collection.
The stunning snaps come after Chrissy has been making the press rounds to promote her latest cookbook in what was her grand return following a very public bully scandal.
Chrissy posted an Instagram album showing her mourning with her husband and mother in the hospital, as well as cradling Jack.
Paired with it was a matching long sleeve blouse and bright pink bag.
She has been the target of backlash since her abusive tweets originally made in 2011 resurfaced online, including one that urged a then 16-year-old Courtney Stodden to kill themselves.
Also part of the party was model Chrissy Teigen and her singer husband John Legend.
At Priyanka Chopra Jonas and Nick Jonas' Diwali party Chrissy adorned a lilac-coloured sari from the same designer, below.
Carrying a bright pink potli, she added an element of contrast to the Indianwear.
