About STC-QST

Leading Apparel Component SUpply Since 1972

Our History

STC-QST is a trusted supplier of apparel and furnishing components, serving manufacturers with a combination of local inventory, responsive service, and global sourcing capabilities since 1972. Headquartered in the Los Angeles Garment District, we support customers with over 85,000 square feet of warehouse space, a dedicated delivery fleet, and dependable access to essential production materials. Our product offering includes interfacing, pocketing, embroidery backing, elastics, bra cups, shoulder pads, waistbands, and home furnishing components. Today, with offices and distribution centers across the United States, Latin America, Asia, and beyond, STC-QST helps brands and manufacturers navigate domestic, import, and blended production models with greater consistency, flexibility, and visibility.
 
Founded in 1972 as Security Textile Corporation by Doug Weitman, STC built its reputation as a leading West Coast manufacturer of shoulder pads and bra cups. In the early 90’s, Doug’s son Brian, a graduate of USC’s Marshall School of Business Entrepreneurial Program, stepped in to take over the family business. As the apparel industry evolved, the company expanded into pocketing, fusibles, and other specialized components to meet changing market demand. In 2008, STC joined forces with QST to form STC-QST — combining decades of domestic expertise with a powerful global supply network.

Diana C.

Bio +

With 20 years of experience in the apparel industry, I specialize in merchandising, product development, and global market strategy. I hold a degree in International Fashion Merchandising Management from the Fashion Institute of Technology in New York.

Throughout my career, I’ve partnered with brands to drive growth through strategic product selection, trend alignment, and strong business models—combining market insight with a focus on product integrity and brand positioning.

At STC-QST, I work closely with clients to select inner components and trims that serve as the foundation of each garment, helping elevate overall quality and performance.

I’m most fulfilled seeing a product succeed in the market, knowing I played a role in building it from the inside out, which is what continues to drive my passion for this industry.
