Started by Erin Bernard in 1998, Lululemon Athletica has been popping up all over the country offering well made and practical athletic wear for sports enthusiasts. Each store reflects the local workout scene and many use local instructors for their classes. The branch in East Hampton opened on Main Street two years ago and its yoga classes have been thriving. The store is also kid-friendly with a small chalk board table for children to draw on while parents shop.
