I don't notice any significant stains, but please refrain from purchasing if you are overly concerned about minor imperfections. There are no pets or smokers in the household. The item has been washed with Laundrin detergent. The size is listed as 6-12 months, but my child was able to use it until they were 2 years old (13 kg). Please note that this is just a reference, as individual children vary in size. There is a name written on the item. It is a full name, so I will black it out. There is also some pilling. Please understand that this item was used by a 2-year-old. I will pack the item compactly for shipping, so please be aware that there may be some folding wrinkles.
