Who We Are
Trusted Turkish Shirt Manufacturer for Global Brands
From our family-run workshop in Istanbul, we produce premium-quality shirts for European and American private label brands, combining craftsmanship with modern production standards.
Private Label Shirt Manufacturer
Founded in Istanbul in 2000 by Mehmet Dag, M.DAG Shirts has grown from a small family workshop into an established shirt manufacturing company serving international fashion brands, wholesalers, and retailers.
With over 25 years of experience, we combine skilled craftsmanship with modern production technology to manufacture high-quality men's shirts tailored to each client's specifications, brand identity, and quality requirements.
From a Local Workshop to a Global Partner
Our story began in 1989, when our founder, Mehmet Dag, started his journey in shirt manufacturing as an apprentice.
After years of hands-on experience in pattern cutting, sewing, and finishing, he established his own workshop in Istanbul in 2000, laying the foundation for what is now M.DAG Shirts.
Today, our team of over 75 skilled professionals produces more than 1,000 shirts daily, serving clients across Europe, the United States, and other international markets.
