About

Purethread is a destination boutique in Shelter Island Heights, New York, offering a refined point of view on modern womenswear.

Each season, established luxury brands and new discoveries are selected across categories to create a cohesive collection defined by quality, versatility, and enduring style. 

Our edit is shaped by how women dress and how a wardrobe evolves, with an emphasis on pieces that feel fresh and relevant now, yet endure over time. The result is a way of dressing that feels confident, easy, and entirely her own.

Our approach is deeply personal. A close connection with our clientele shapes the experience of the boutique—a welcoming and inspiring place to discover, explore, and spend time.

MEET OUR FOUNDER

Jill Heller

Jill Heller is the founder, buyer, and creative force behind Purethread. 

Her career in fashion is rooted in a family legacy of apparel manufacturing. Jill’s own retail career began in Manhattan, where she opened her first boutique on Columbus Avenue, followed by a luxury women’s boutique in Westchester County. 

In 2010, Jill founded Purethread, bringing her experience and instinctive eye to a highly personal approach to retail—thoughtful curation, established designers alongside new discoveries, and an understanding of what women truly want to wear.

Discovery remains at the heart of Jill’s approach to buying. She brings together established brands, emerging designers, and unexpected finds, then merchandises them in a way that allows each collection to become part of something larger, creating a store that feels fresh, relevant, and continually evolving.

Jill’s approach has always centered on how a woman feels in what she wears. Her eye for proportion, ease, and individuality shapes each collection, while her continued presence in the boutique keeps her closely connected to the women she buys for. Those relationships, and an understanding of how women actually live and dress, remain at the heart of her point of view.

Jill and her work have been featured in The New York Times, Vogue, Elle, Hamptons Magazine, The Purist, Harper’s Bazaar, Oprah, and Organic Spa Magazine, among others.
