About Equation
Equation is a modern women’s
boutique where elevated fashion meets personal connection. Founded by Susan Sun, Equation takes its name from Einstein’s equation and the shared initials of her four children’s names, and has always been rooted in intention, family, and individuality.
Since opening in Edina in 2015 and expanding to Excelsior in 2025, Susan has shaped Equation into a destination for elevated everyday women’s fashion. With a strong focus on styling and customer experience, Equation encourages women to experiment with their personal style while staying polished and intentional.
Featuring brands such as Ulla Johnson,
Zadig et Voltaire, SEA NY, Jenny Bird, Anine Bing and more, Equation’s balances everyday luxury with wearable cool… Think contemporary silhouettes, refined essentials, and statement pieces that feel both effortless and directional.
We pride ourselves on knowing our customers and helping them evolve wardrobes that feel authentic and personal. Shopping with us is meant to feel welcoming and inspiring, like a neighborhood boutique with a fashion insider’s point of view.
We’re grateful to be part of your style story!
