Celebrity stylist Erin Walsh dishes on Sarah Jessica Parker's style

Erin Walsh didn't always plan on being Hollywood's go-to stylist.

In celebration of Pronovias' latest 'Evening Essentials' line, AOL sat down with Erin Walsh at the brand's flagship store in New York City, where the celebrity stylist hosted a master class about the collection.

"I'm excited about this collection because it speaks to so many women, both silhouette wise and in terms of viable lasting options in your wardrobe. None of these feel like fast fashion or one-season-wonders. The way that they were able to do such a classic collection is such a modern and elegant way is not an easy feat. I was extremely impressed," Walsh said of Pronovias' new evening line.

After moving to New York in hopes of becoming an actress, Walsh landed a job at Vogue which ultimately led her into the fashion scene. From Maggie Gyllenhaal to Thandie Newton and Lily Aldridge, Walsh's roster of A-listers is packed, to say the least, but one actress, in particular, was a 'pinch-me' moment for Walsh.

"When I found out I was working with Sara Jessica Parker I think I almost died. When I started working with Kerry Washington several years ago, I only had a couple of red carpet clients and she sort of took a chance on me and I was like 'is this really happening?' and then all of these things came up and it was like a runaway train for a while, it was really fun."

Erin is not only responsible for the former "Sex and The City" actresses epic Met Gala look, but the two recently worked together on a dress she wore to the New York City Ballet's Fall Fashion Gala alongside hubby, Matthew Broderick. The red couture gown made headlines was even dubbed her 'best look yet.'

"With the ballet specifically every year, its a collaboration with the designers and they designed costumes for the ballet and then we customized that dress by Giles [Deacon], who is pretty much running a couture house at this point. He is an exquisite man and we were very lucky to do that," Walsh explained of the breathtaking look.

"One of my favorite parts about doing all of this is starting these relationships with these brands and designers and figuring out what kind of stories you want to tell. Also, getting to work these designers, not just for the occasion but making it a narrative. How many different ways can we tell their brand's story and the women that they are speaking too? If it just happens to be on a red carpet with SJP or whoever that person is, it's speaking volumes to the kind of women that so many women want to be," she added.
