Meet Mainstream's Founder, Marie! She started the company as a home-based business back in 1991, with a simple dream: comfortable, stylish clothing for busy women, brought right to their door. 35 years later, that dream is still going strong. Come celebrate our Birthday with us at your local Mainstream Boutique, Saturday, October 24th.

🎉 Congratulations to Mainstream Boutique Sheboygan on 7 amazing years! This year also marks a special milestone — it's officially been one year since mother-daughter duo Christi and Alayna, who own the Janesville location, took the reins as owners in Sheboygan too, continuing the legacy Dana built. Here's to seven years of style and community, and to a great first year for Christi and Alayna as owners. Congratulations — we're so proud to celebrate with you! 💛

Congratulations to Barb and Erica — the mother-daughter duo behind Mainstream Boutique Hudson and Canton, Ohio — on being voted Greater Akron's #1 Clothing Store! 🎉🏆 This is such a huge win, and such a well-deserved one. From day one, this team has poured so much heart into building not just one incredible store, but two — and it shows in every detail, from the styling to the way every customer is welcomed like family. None of this happens without an amazing team on the floor every day, and none of it means anything without the incredible customers who show up, shop local, and make this community what it is. Congratulations, Barb, Erica, and the entire Hudson and Canton team — this title is so well earned, and we couldn't be prouder to celebrate you today! 🥂💕

Here’s to an incredible first year, Cindy — we can’t wait to see everything year two has in store! 💕
