The floral pajamas are size 80 and easy to use with elastic at the neck, wrists, and ankles. The Wanwan and U-tan costume has no size listed, but it was worn during the time the matching pajamas were worn. There are some pills and black marks. One button is missing from the bottom of the Wanwan costume. I'm not good at sewing, so someone who is skilled, please. Thank you for looking.
