Mumu, caftan, nightgown, housedress, all-day dress... we choose to call it the "ALWAYS Dress", because it cute enough to wear all day, and comfy enough to wear all night, ALWAYS. The coziest, buttery fabric that you won't want to take off.
Loose, oversized fit. Don't worry about your size too much, just look at the measurements, give yourself several inches to spare (depending on how you want it to fit) and sit back and wait for the only dress/nightgown you will ever want to wear again.
Functional snaps at the neck for easy nursing and/or just to easily take on and off. A slit in each side at the bottom of the dress, and 2 big adorable pockets to tote the essentials around in... aka.. bathtub treats and your phone.
Sizing can vary an inch, give or take, because of the stretch in the fabric.
