Rosa Grundmann

I’m a Berlin-based freelance fashion designer with a deep passion for creating modern, functional, and forward-thinking apparel. My expertise lies in the intersection of street culture aesthetics, performance-focused sportswear, and technical outdoorwear — blending style with innovation.

With several years of industry experience across womenswear, menswear, and unisex design, I specialize in the development of modular layering systems, ergonomic cuts, weather-adaptive silhouettes, and smart material selection. From high-stretch compression fabrics and moisture-wicking jerseys to 3-layer bonded shells with taped seams – I know how to build garments that perform and stand out. In my designs I combine functionality with style and comfort to develop the best possible solutions. For outdoor & sport- brands, same as for street style brands with high demands on function next to urban shapes.

My process is hands-on and detail-oriented: I support brands from concept research and trend analysis through to tech pack creation, material sourcing, fit development, and pre-production. I’m proficient in visualizing your ideas with Adobe Illustrator and I bring a strong eye for proportion, function, and brand identity.

Whether you’re a start-up looking to shape your first capsule or an established label needing freelance support – I deliver creative, technical, and reliable design services tailored to your needs.

Let’s bring your next collection to life.
