HQI Workshop is a garment design and creative agency specialising in the design, development and production of functional garments for the fashion and performance-wear sectors. Located in Bangkok, Hong Kong, London and Tokyo, we offer clients a complete solution-oriented service from creative direction and brand creation to garment design and sample development to manufacturing and material sourcing.

HQI Workshop is rooted in the fundamental belief that well-designed functional garments are timeless and transcend fashion trends. Our agency combines comprehensive knowledge and experience in creating innovative modern clothing with an extensive reference garment archive and knowledge of classic vintage and contemporary functional fashion. We place a strong design focus on garment craft, particularly technical garment construction and the industrial engineering of garments using modern techniques such as thermal bonding, laser cutting, sealing taping, seamless technology, body-mapping and the application of performance fabrics. For activities which require rigorous uncompromising use in extreme climatic environments, we can create custom high-performance garments using a methodical and well-refined field testing method in collaboration with athletes and specialists in the field.

We can also help clients with the sourcing and development of fabrics and trims through our extensive network of material suppliers - from vintage luxury fabrics to cutting-edge technical fabrics to innovative sustainable fabrics. For specific functional or aesthetic requirements, we can develop bespoke fabrications in collaboration with industrial partners. 

Laser-focused on attention to detail, we believe that garment designers must collaborate in perfect synergy with brands, material suppliers, manufacturers and craftspeople to find intelligent design solutions and create unique high quality, high-performance clothing.
