We have *details* about the wedding dress Blake Lively’s friend and former assistant wore last weekend

When you’re friends with style queen Blake Lively and you’re tight with Marchesa designer Georgina Chapman, you know you’re going to look like a total goddess on your wedding.

That was definitely the case for Jessica Snyder, Lively’s best friend and former assistant, who married her bae Selwyn Cummings in a custom Marchesa gown over the weekend.

Lively shared a few snaps from her friend’s big day on IG, calling Snyder “the best friend I could ask for” and obsessing over the “killer details” on the gown.

She is not wrong about that dress!

We’re swooning!

Snyder was Lively’s assistant from 2010 to 2013, when she moved on to a position as Chapman’s personal assistant at Marchesa. She remained at Marchesa until 2015 and has a close relationship with Chapman and the brand. So close, in fact, that Chapman and her co-designer, Keren Craig, custom-made Snyder’s wedding gown — which took about 500 hours to create.

“I couldn’t be more thrilled for Jessica,” Chapman said in an interview with People. “She was my assistant [and] has grown into a dear friend. She made the most beautiful bride and I was honored that she chose to wear a custom Marchesa gown for her special day.”

Lively is no stranger to the Marchesa brand, either. She frequently wears the designer on the red carpet and was even clad in Marchesa when she married husband Ryan Reynolds back in 2012.

You’d be hard-pressed to find a full-length photo of the frock, though — the couple was super private about their nuptials and didn’t allow anyone to bring their phones into the event!

We couldn’t be happier for Snyder and her love, and it’s so nice to see Lively supporting her friend (just days after giving birth!) Congrats, Jessica!
