This is a set of three short-sleeved undershirts purchased at Birthday. There are faint milk stains on the collars of the shirts, except for the green polka-dot one. Newborns need frequent diaper changes, so I often used these short-sleeved undershirts. Would these be suitable for spares? Please refrain from purchasing if you are overly concerned about the condition. - Color: White - Material: Cotton - Style: Short-sleeved undershirts - Size: Newborn 50-60cm Thank you for looking.
