Classic white button down by Hatch maternity. Size 1 which is their small size. But has tons of room to follow you through each trimester. EUC Lightweight cotton shirting, HATCH’s spin on the classic button down hits all the marks: a crisp collar, inverted pleat at center back and stiff banded cuffs with a bias body, gusset piecing and a notched hem that flatters as your shape changes.
