The product description says 12-18M. My child wore these at age 3. I bought these for when there were specified chinos or similar pants at the nursery, and they were worn about twice. They have been stored at home. No name written. There is elastic for adjusting the waist. There are no noticeable stains, but please understand that these are used items and consider purchasing. How about these for those who want to get them at a low price? Recycled packaging materials may be used for shipping. Please comment if you have any questions.
