Meet the Owners

Hi, from Mainstream Boutique of New Lenox! We are so happy you found us! We are locally owned and operated by a mother-daughter duo - Penny & Amanda McKeller, making us a multi-generational women's clothing boutique. Our passion for fashion and encouraging women to feel beautiful in their own skin is what drove us to open our doors in 2020. We look forward to meeting you!

I absolutely love shopping at Mainstream! Not only are the clothes so comfy and cute but the staff is amazing. I love all the trendy styles. The Mac & Me jeans are the comfiest jeans I own! All the girls are so helpful and welcoming from the moment you walk in the door. ❤️

Love this store! So many cute options to choose from. I love supporting local business and I'll be going back here for sure.I really enjoy talking with the girls that work there - I was only in one time before, but they remembered who I was. That special touch really meant a lot to me.
