Size guide & fit →

  • Breathable cotton-gauze weave: Light, airy double-gauze with a soft hand-feel that stays cool on warm summer nights and is gentle against little cheeks.
  • Make every moment match: Coordinating mother and daughter sets made for brunch, birthdays, holiday cards, and cozy family bonding — effortless matching, photo-ready in seconds.
  • Good Night Song of the Sea print: A dreamy watercolor ocean of whales, sea turtles, jellyfish, mermaids, stingrays, and coral on a soft cream ground — picture-perfect and quietly whimsical.
  • Classic design details: Notched collar, full button-down front, contrast dusty-blue piping along the placket, cuffs, and hem, and pull-on elastic-waist shorts for easy movement.
  • Easy care & breathable: Machine-wash cold, tumble dry low. The open gauze weave keeps airflow high and wrinkles low.

Our Good Night Song of the Sea mommy-and-me pajama set turns bedtime into a drifting ocean lullaby. The cream cotton-gauze is painted with watercolor whales, sea turtles, jellyfish, mermaids, stingrays, and swaying coral, finished with soft dusty-blue piping that frames the notched collar, cuffs, and hem. It is the kind of print that belongs in a seaside cottage reading nook — gentle, nostalgic, and quietly whimsical.

Wear it for slow Sunday brunches, summer sleepovers, beach-house mornings, birthday pancakes, and those holiday-card mornings when the whole family needs to look picture-perfect without trying. The button-down top and elastic-waist shorts move easily from pillow fights to pancake-making, and the full mother-and-daughter size run means nobody gets left out of the twinning moment.

Key Features:

  • Coordinated mother & daughter fit: Identical under-the-sea print in adult and child cuts so every family photo matches effortlessly.
  • Breathable cotton-gauze weave: Lightweight and airy for warm-weather sleep and summer travel.
  • Button-down top: Classic notched collar, contrast dusty-blue piping, and real buttons down the front.
  • Pull-on shorts: Soft elastic waistband for easy on-and-off and all-night comfort.
  • Inclusive sizing: Girls 2–10 Years and Mothers S–XL — add both to cart to complete the set.

Add the mother size and the matching children's size to your cart to make every moment match — bedtime, brunch, and every snapshot in between.
