Worn only once for a few hours on the day of the birthday, and then stored after home cleaning. There are no noticeable stains, so it can still be worn. It's a shame to throw it away after my child outgrew it, so I'm offering it to someone who can wear it ♡ It says 18 months to 24 months. My child is slender, so they were able to wear it until they were about 3 years old!
