Clothing - Fashion Importers, Turkey Import Companies

I want to produce t-shirts in Türkiye I am looking for a textile company. I want to buy. It can also be the finished product, fabric halide or "I want to have classic single color t-shirts produced. For this, I request catalogs from companies that have fabric or products." I will start a company, it will be somewhere in between, I will either buy the fabric, find a tailor and produce t-shirts. Either I will find the t-shirt and market it.
