The plain ones on the right are from Miki House. Two-piece short-sleeved undershirt set. - Size: 50 - Made in Japan - Design: Front-opening type - Color: White - Features: Set of 2 Even in winter, babies sweat, so I used to dress them in these in combination with thick winter undershirts. How about these for a change of clothes? There are no noticeable stains, but they have been stored at home, so I would appreciate it if you could understand. To reduce shipping costs, I will fold them for shipping. Thank you for looking.
