What is a cute alternative to Lily Pulitzer clothing that is similar?

I am going through rush in the fall and Lily is the perfect style dress for it. Brightly colored, well made dresses, etc. I am tired of looking through a bunch of cheaply made dresses. The problem is, everyone will be wearing Lily dresses so I was wondering if anyone knew of a similar line so that I will have unique dresses. I don't care if it is expensive. Thanks!
