Founded in 2001 by Ingrid Carney when she was pregnant with her daughter Isabel, this maternity brand offers supercool styles for every step of the journey from pregnancy through motherhood. For all you sporty mama's, this fitness dress is calling your name. The Ribbed Exercise Dress is made from thick ribbed material, but it still maintains a breathable silhouette. Plus, it features built-in biker shorts—no slip ups here(!)
