About us

The Dirty Seahorse specializes in designing and manufacturing workwear specifically tailored to the needs of women in skilled trades.

Recognizing a critical need for suitable workwear tailored to women in skilled trades, Dianne Finnigan, Founder & CEO of The Dirty Seahorse, embarked on a journey to address this disparity in the market.

By engaging directly with women in trades through comprehensive surveys and interviews, The Dirty Seahorse embarked on a mission to revolutionize workwear for women. With a commitment to inclusivity and empowerment, the company has forged a unique path, prioritizing the input and needs of its target demographic at every stage of development.

The ethos of “Built by women for women” underscores the core philosophy of The Dirty Seahorse. Through collaborative efforts and a dedicated focus on user-centric design, the company has meticulously crafted a range of clothing solutions tailored to the specific requirements of women in the trades. Each product is imbued with insights gleaned directly from the community it serves, ensuring functionality, comfort, and durability.

Driven by a passion for equity and excellence, The Dirty Seahorse maintains its steadfast commitment to redefine industry standards and empower women to thrive in traditionally male-dominated fields.
