This is a thin, easy-to-wear top with a border pattern, making it versatile for various outfits. It's a free size, but I felt it might be a little small for a child who wears size 90. *Please note that this is just my personal opinion. Please understand that this is a used item. I will try to ship it as soon as possible, but please be aware that there may be delays as I have a 2-year-old child. Thank you for looking. Type: T-shirt
