If you’ve been watching “The White Lotus,” the hit series on HBO, you’ve probably noticed — or possibly become obsessed with — the luxurious clothing worn by Parker Posey’s character, Victoria Ratliff.

It’s resort wear par excellence, perfect for a rich lady from the South who values comfort — and wants to be extra cozy when she’s lounging at a fabulous villa in Thailand. Victoria Ratliff has been known to pop a few pills on vacation, as well, to help smooth the rough edges when she’s away from her beloved home in North Carolina.

Posey has become a fan favorite on the show during Season 3, playing the hilariously entitled mother of a clan that encounters family strife and gets tangled up in a murder mystery at a fancy Thai hotel.

“Parker is probably one of the most collaborative actors in the cast, so we got on the phone and talked a lot about what she would wear,” costume designer Alex Bovaird said in an interview with Who What Wear. “She doesn’t really go to the pool, she doesn’t go to the beach, she just sort of hangs around being comfortable, getting massages, getting treatments, staying in her comfort zone. So she has these big, flouncy caftans. She’s very comfy.”

Posey’s top-notch acting skills are on display, of course, but she’s also been making a major fashion statement on “The White Lotus,” thanks to Bovaird and her secret weapon: Alabama’s Susan Dumas, who’s been called “the caftan queen of Birmingham.”

“We were inspired by a lady from Alabama who sells vintage clothes and caftans, and she gave me a bit of insight into her country club world and how fun the women are down there,” Bovaird told Who What Wear.

Bovaird also mentioned Dumas’ influence in an interview with Vogue, which pointed to Victoria Ratliff’s “floaty cover-ups, perfect for sipping mint juleps by a members-only pool.”

Dumas, who sells vintage clothing from her home in Mountain Brook, clearly is having a moment on national television, even if casual viewers of “The White Lotus” don’t recognize her name. She acknowledged the connection in a recent Instagram post that said:

“How many times have I said it but @alexbovairdsprouse (the brilliant costume director for White Lotus) is deservedly on top of the world right now but is so wonderful and kind that she is giving me my 15 minutes too. Every time she mentions me in an interview, I have to remind myself that I still have to do the dishes and laundry because I feel like I might be getting too big for my britches!! It’s one thing to let me throw my clothes in the show. It’s another for Alex to mention me in her fancy interviews!! So, thank you, Alex for being the BEST and I can’t wait for you to come to Birmingham and hang out with my cool country club friends.”

From what we can tell, Dumas had an Etsy shop for a few years, called I Wish I Could Keep It All. She now focuses on periodic shows at her home on Old Leeds Road, serving as a consultant and fashion guru for folks who attend. Dumas also showcases vintage clothing in her posts on Instagram and Facebook.

Her collection is filled with “sexy halter dresses, muumuus, timeless evening gowns, and delicate, detailed tops,” according to a 2018 feature story in Mountain Brook magazine. “Printed silk scarves, woven leather belts, chunky costume jewelry and embellished bags are carefully on display, ready to be thrown over the vintage garment of a shopper’s choosing.”

Dumas, who grew up in Selma, has traced her love of vintage clothing to her teen years, wearing items she found in her mother’s closet. Her fondness for vintage apparel increased during time spent in San Francisco, and continued when Dumas moved to Birmingham.

“Throughout my life, I have always loved being a little different, and vintage clothes help me do that,” Dumas said in a recent interview with StyleBlueprint. “My postman, Jeff, got me started in the vintage clothes business. He stopped by one day and told me I should try to sell some of my clothes ‘because you don’t do anything and you have a real interesting style.’ It was intended as a compliment … I think. To be fair, I did have a huge collection. When you buy vintage clothes on the internet, one piece fits, but then ten don’t. So, I had the inventory.”

Her first home show was a success, Dumas said, and her business grew from there. She maintains an extensive collection in the basement of her house, and is especially fond of fashions from the 1960s and ‘70s.

“I mainly buy vintage American caftans, Middle Eastern caftans, black tie dresses, Mexican Puebla dresses, blouses, secretary dresses, jumpsuits, Hawaiian designer dresses, skirts, palazzo pants and accessories, all from the 1960s and 1970s,” Dumas said in a 2021 interview with AboutTown. “I love lots and lots and lots of color but other than that, anything goes. I buy so many different styles of clothing so that everyone can find their own groove in the collection.”

If you’re wondering how Dumas became a caftan guru for “The White Lotus,” she explained the fashion hookup to StyleBlueprint.

“That’s the craziest thing that has ever happened to me!” Dumas said. “My friend went to a wedding where she wore a lot of my clothes. Her cousin apparently liked them and told her sister-in-law about them. Her sister-in-law, Alex (Bovaird) Sprouse, happened to be the costume designer for ‘The White Lotus.’ I guess she followed my Instagram, where I post my pieces that will be in upcoming shows. I came home from a big night out to an email from Alex saying she’d like me to help costume the upcoming ‘White Lotus’ season. Would you believe that?”

Viewers will have one more chance to see Parker Posey in resort wear inspired by Dumas. The Season 3 finale of “The White Lotus” is set for Sunday, April 6, at 8 p.m. CT, airing on HBO and streaming on MAX.
