Our Story

Welcome to Mainstream Boutique of New Lenox!

We’re so happy you found us! Mainstream Boutique of New Lenox began as a dream brought to life by a mother-daughter duo, Penny and Amanda McKeller, whose love for fashion, family, and community shaped the heart of this boutique.

Where It All Started

While living in Sioux Falls, South Dakota, Amanda discovered the Mainstream Boutique franchise and was instantly drawn to its unique, family-centered culture. When she moved back to Illinois in 2019, she and Penny began exploring the idea of opening a business together. With their shared passion for fashion, they knew a women’s boutique was the perfect fit—and Mainstream Boutique aligned beautifully with their values of family, love, and connection.

A New Chapter

In 2025, the boutique entered its next phase under the ownership of Fiona Gill, who is deeply honored to build on the strong foundation Penny and Amanda created. Their legacy of friendship, inclusivity, and confidence remains at the core of who we are.

While the ownership has transitioned, the boutique’s spirit has not changed:
Women of all ages, sizes, and stages deserve to feel confident, beautiful, and valued.

Carrying the Legacy Forward

Fiona brings her own passion for empowering women, community connection, and simple, confident style. Alongside our wonderful team, she is excited to:

✨ Continue the welcoming, relationship-driven culture the McKellers built
✨ Introduce fresh experiences, events, and new styles
✨ Grow our presence in the community—online and in person
✨ Make every moment memorable for the women who walk through our doors
