About

Hi, I’m Jussi Siivonen, an apparel designer and brand developer with over 15 years of experience turning concepts into market-ready products. I’ve led end-to-end brand development, including the 2024 Brasil Beauty launch that generated €900,360 in revenue in its first year and accounted for a large share of company sales.

I excel at technical garment construction, inclusive sizing (S–4XL), and working with international factories to ensure high-quality production and minimal returns. I’m passionate about blending creative design with practical production processes to build brands that look great and fit well.
