We love Nantucket summer fashion, but Reese Witherspoon just proved that transitional style just might be even more swoon-worthy. Her striped dress is the definition of East Coast class, channeling playful, preppy energy in an effortless way - and we found the coveted look for just $36 on Amazon. This everyday striped shirt dress appears just as high-end as Witherspoon's due to a loose yet tailored fit that makes it as comfy as it is sleek.
