This is a Sesame Street setup featuring Elmo and Cookie Monster. The size is 12M. I bought it in the US last year. It's fleece-lined, so it's warm enough to wear this time of year. It's even cuter when worn as a set! There don't seem to be any noticeable stains, but there is some pilling overall. Please note that this is a personal inspection, so there may be oversights. I hope you can use it for a short walk or as pajamas. Thank you for looking.
