Our Story

Tailored for female leaders

"What started as a personal styling studio quickly became something more. I saw that the women I worked with didn’t just want outfits—they wanted to show up with confidence, visibility, and influence. That’s when I realized: style isn’t just about clothes: it’s a strategic tool for leadership. And that’s why I built Costigan."

- JULIANNE COSTIGAN, FOUNDER & CEO
