When the dress code is Markarian, you know you're in for a fabulous night...

Last evening, Markarian's Alexandra O'Neill and Chief Merchandising Officer of Saks Fifth Avenue, Tracy Margolies, hosted a batch of the city's most stylish for an en plain air dinner at The Terrace at L'Avenue at Saks in celebration of the fashion brand's new Resort 2023 Collection.

Everyone from Nicky Hilton and Maye Musk, to Finnegan Biden, Charlotte Groenveld, Lydia Fenet, Cece Barfield Thompson and Lili Buffet was in attendance, modeling a fashionable parade of Markarian frocks. 

An ode to sequins, if you will.

So, curious to see who wore what?
