Maternity Size 2-Way Long Sleeve Cotton One-Piece Pajamas [Before & After Pregnancy] [Hospital Preparation] Colors: Charcoal (Gray) / White / Striped Made of 100% cotton for a comfortable feel, can be used as maternity wear and nursing wear. The one-piece style is also recommended as hospital wear. By fastening the buttons at the crotch, it becomes a romper style, which was good because the hem didn't ride up while sleeping, and the buttons for rolling up the sleeves were convenient for bathing and washing. Please understand that there is some wear and tear as I wore it with affection. Short-sleeved types are also on sale.
