Claire Sullivan is a New York–based fashion designer who founded the label Miss Claire Sullivan after working at Vaquera. Her independent practice grew from a custom commission in 2021 and developed around one-of-one garments, intuitive draping, and close collaboration with individual clients.
Her career did not follow a conventional route from fashion school to an established house. Sullivan gained early experience at Eckhaus Latta, advanced from intern to co-creative director at Vaquera, and then left during the COVID-19 period without a settled business plan. By 2026, her namesake label had become a CFDA/Vogue Fashion Fund finalist.

Childhood Sewing Led to an Interdisciplinary Education
Sullivan grew up in Richmond, Virginia, in a family she described as largely connected to medical professions. Her own interests moved in another direction. She said wearing a princess dress at five became her first significant fashion memory, and the sense of fantasy associated with childhood dress-up remains in her label.
Her mother taught her to sew when she was seven. Sullivan initially practiced by making small pillows before progressing to clothing, which she said she began creating at 16. While still in elementary school, she researched fashion colleges and imagined a future centered on clothes.
She later attended the School of the Art Institute of Chicago because its interdisciplinary structure allowed her to work beyond a single design category. Her studies involved fiber, materials, sculpture, and performance. Her work with those disciplines later informed the volume, physical construction and sense of character visible in her garments.
Eckhaus Latta and Vaquera Shaped Her Industry Experience
Before her major role at Vaquera, Sullivan interned at Eckhaus Latta. She has described that experience as her first close look at how an independent fashion brand operates.
After moving to New York in 2016, she responded to an internship opportunity at Vaquera. The collective invited her to remain after one season, and she eventually became a co-creative director. Sullivan credited the label with changing how she approached fashion construction. Although she had received traditional training, Vaquera encouraged her to challenge established rules and work through a more experimental process.
Collaboration was equally important. Working alongside other creative directors taught her how to develop ideas collectively, a practice she later carried into her custom commissions.
Vaquera was named among the 2018 CFDA/Vogue Fashion Fund finalists while Sullivan was part of the team. That recognition belonged to the collective rather than to her later namesake business, but it formed part of her early professional record.
Leaving Vaquera Created an Uncertain Turning Point
Sullivan left Vaquera during the COVID-19 period. She has spoken openly about the uncertainty surrounding that decision, explaining that she had no detailed plan for what would come next. She knew she wanted to keep creating clothes and working with people she valued, but an independent label wasn’t yet fully mapped out.
A request from her friend Tourmaline provided the first practical step. In 2021, Tourmaline asked Sullivan to style an art project. After hearing the brief, Sullivan decided that creating custom ensembles would serve the project better than selecting existing garments.
She then began making additional pieces for herself. Interest from stylists and other clients followed, gradually turning an individual commission into a custom-couture practice. Vogue identifies 2021 as the founding year of Miss Claire Sullivan, while separate reporting places the beginning of her custom-client work in August of that year.
A later lookbook documented garments made from 2022 onward. That date refers to the work assembled for the presentation, not to a replacement for 2021 as the label’s supported origin.
Custom Garments Became the Center of Her Practice
Miss Claire Sullivan initially developed through one-of-one pieces created for particular people and occasions. Instead of designing a standard collection and then finding customers for it, Sullivan often began with the wearer, the intended setting and the feeling the garment needed to create.
She has described this approach as something close to a service. The client is not simply receiving an adjusted version of an existing design; the person and the occasion influence the garment from the beginning. Sullivan has said that seeing someone respond positively to a piece made specifically for them is among the most rewarding parts of the process.
Draping is central to her work. She often develops shapes directly on the body rather than relying entirely on a flat drawing. At times, she uses her own body to understand where fabric should fall, gather, or tuck. The resulting clothes frequently employ volume, corsetry, sweeping fabric, and exaggerated proportions.
Her early practice was often described as exclusively custom, but the business has since expanded. The official Miss Claire Sullivan website now presents both fully custom services and selected made-to-order products.
Despite that expansion, Sullivan has continued to emphasize careful construction. In a 2026 interview, she said her studio deliberately works slowly, tailoring each element to both the client and the moment rather than prioritizing rapid output.
Major Commissions Expanded the Label’s Public Profile
One of Sullivan’s documented 2023 commissions was a Met Gala outfit for Vogue editor Chioma Nnadi. The design combined a ball skirt, corseted bodice, pinstripes, and an asymmetric sleeve. It was developed after studying archival garments connected with that year’s event theme.
Later that year, Sullivan created a newspaper-print dress for Sarah Jessica Parker’s Vogue digital-cover project. The commission involved Vogue stylist Jorden Bickham, director Bardia Zeinali, and graphic designer Jakob Weinzettel.
Instead of reproducing an existing dress, the collaborators assembled imagery and text from Parker’s American Vogue covers and articles. They transferred the material to silk crepe, which Sullivan draped over a built-in corset before adding black tulle. She described the assignment as one of her favorite pieces.
Her practice also moved into a larger runway collaboration in 2024. Ganni creative director Ditte Reffstrup invited Sullivan and designer Nicklas Skovgaard into the company’s studio for its Spring/Summer 2025 Paris presentation. They co-created looks that combined the designers’ perspectives through details including volume, frills, florals, and sportswear references.
In July 2025, Sullivan presented a 20-look retrospective rather than a conventional preview collection. The lookbook gathered custom garments produced since 2022, including pieces created for public appearances and editorial work. It allowed the designer to present commissions previously seen separately as one connected body of work.
Creative Values Guide Both the Clothes and the Business
Sullivan places fun, fantasy, and storytelling at the center of her design practice. She wants the person wearing a garment—and the people seeing it—to experience the sense of play built into the piece. Childhood dress-up remains a recurring reference, but the finished work is tailored to adult clients and specific occasions.
Her creative process also depends on knowing when to step away. Sullivan has said that when an idea stalls, she may leave fashion work temporarily and turn to movement, walking, nature or stillness. In a 2025 interview, she described meditation, exercise and gratitude writing as parts of her morning routine. She also emphasized giving herself time when ideas don’t arrive quickly.
Operating an independent label brings different demands. Sullivan identified the constant movement between creative decisions and business responsibilities as one of the hardest parts of her role. Rising costs and the expense of producing clothes in New York add further pressure.
She nevertheless regards running the business as a privilege. Rather than following a rigid seasonal calendar, she wants fashion to leave more room for creativity, craftsmanship and work released at an appropriate time.
Custom fitting also supports one of her stated professional values. Sullivan has said body diversity is central to Miss Claire Sullivan because each client receives clothing shaped specifically around their body.
Independent Recognition Marked a New Stage in 2026
On June 2, 2026, the Council of Fashion Designers of America officially announced Claire Sullivan among the ten 2026 CFDA/Vogue Fashion Fund finalists. The selection placed her independent label in the program eight years after Vaquera reached the finalist group.
The distinction between those two milestones is important. The 2018 recognition concerned the Vaquera collective, while the 2026 selection named Claire Sullivan of Miss Claire Sullivan. The announcement established finalist status, not a Fashion Fund win.
Her public work continued that June with an upcycled dress made from New York Knicks T-shirts. Friends helped source shirts in different colors, and Sullivan began arranging the material directly on her body. Rama Duwaji wore the completed dress during New York’s championship parade on June 18.
In July, a sponsored Hypebae feature presented Sullivan’s collaboration with adidas around the ADIZERO EVO SL Zip. She translated elements from the footwear—including its zipper, stripes and lightweight construction—into a couture look featuring tulle, an oversized zipper and an extended train. The commercial project followed her appearance in an earlier adidas campaign.
Her Couture Label Grew Through a Personalized Approach
Miss Claire Sullivan is defined by garments developed around individual wearers rather than a conventional seasonal range. That approach now extends to bespoke commissions, made-to-order pieces, and select collaborations, keeping draping and close client involvement at its center.
The 2026 CFDA/Vogue Fashion Fund selection gave Sullivan’s independent practice recognition under her own name, separate from Vaquera’s 2018 finalist appearance.
