Lululemon light blue hoody sweatshirt. Maybe size small/medium

This is an old one but in almost new condition. So strong, thick and heavy but really cozy on. No tags! I think its an xl boys. I wear an ex small and it fits me like an extra large boy’s or slim medium men’s. Please check measurements. One tiny spot on bottom in picture 9 that I did not try to get out. Looks removable. At firstst glance the color lookss like a really faded denim but a little green. Would be like an light aqua blue. Like water beach blue. It fits my 5’2 13 year ld son really nice but he does not like the color. I was going to see f I can dye black or gray but do not have the time.
