Hey, I’m Katie.

A woman shopping for clothes in a store, looking at a clothing rack with a smile.

I offer end-to-end apparel design and development services for brands focused on creating thoughtful, high-quality activewear.

My Approach

Your partner in bringing your vision to life

I take a collaborative and strategic approach to every project, working closely with clients to define their target market, and product goals. From there, I translate trend insights into commercially viable designs that make sense for their niche—prioritizing fabric, fit, and functionality over unnecessary complexity.

My services include concept development, fabric sourcing, design, fittings, and direct communication with manufacturers. I remain hands-on throughout the entire process to ensure each piece is developed with intention and brought to life at the highest possible standard.

Whether you are launching a new brand or evolving an existing one, I provide the clarity, structure, and industry expertise needed to move from idea to finished product with confidence.
