Organic Pima Dress


The oversized sleep t-shirt which looks killer as a dress, finally is one. Functional, comfortable, and way more flattering than that holey thing you’ve been hanging on to since college. This dress is the answer to all of your ratty too-big t-shirt woes in the softest-ever Organic Pima Cotton. Layer under our Pima Long Cardigan for a look that’s anything but basic.

  • Longer, raglan-style sleeves
  • Kangaroo pocket for all of the essentials
  • Slightly more substantial weight to eliminate sheerness
  • Great for hot sleepers
  • Machine wash, cold + lay flat to dry
  • 100% GOTS Certified Organic Pima cotton. More on our Organic Pima Cotton HERE.
