Meet the Team!

We are Mainstream Boutique! Started by a mother daughter team, Mainstream Janesville opened its doors in 2020 with the goal to empower and encourage women of all ages through fashion. In 2025, we had the pleasure of taking over the Sheboygan location. We can't wait to meet you!

YOU ARE SO LOVED
