I'm Jonathan Mitchell, a freelance fashion designer and founder of J Mitchell Design. With over 20 years of experience, I specialise in sportswear, activewear, streetwear and sustainable fashion. I’ve worked with global brands like Puma, Umbro and Maserati MSG Racing, as well as startups looking to launch something unique. Based in Yorkshire and working with clients worldwide, I manage the full design journey—from mood boards and trend research to CADs, tech packs and production. My focus is on turning creative ideas into commercially successful fashion collections. Through my blog and LinkedIn, I also share tips for fashion startups and freelancers—offering practical, real-world insights into the fashion industry. Whether you’re building a brand from scratch or scaling your product range, I’m here to help bring your vision to life with expert fashion design support.
