NYC-based HATCH specializes in easy, superversatile pieces that a mama-to-be will want to wear long after the baby is born. A pointelle nightgown in crazy soft cotton that's so pretty you can greet guests in it. Bonus: The stretchy fabric has so much give that you don't even need to unbutton the placket to nurse.
Recommended sizing based on your pre-pregnancy size: 0 (XS/S), 1 (S/M), 2 (M/L), 3 (L/XL).
