My mother bought this for me, but I never wore it, so I've kept it with the tags on. I'm selling it because it's a waste to just keep it! The neck and inside are fleece, so it looks warm♩ This kind of vest can be worn for a long time, from around 1 to 4 years old☺︎ For those who understand that this has been stored at home. I will compress it to make it smaller for shipping. Please feel free to ask any questions. Thank you☺︎
