Vintage Lee Denim Jacket kids size Large

Cute vintage 80’s or 90’s Lee snap denim jacket. In good condition—a few loose threads. Marked size large. Looks to fit like a 4/5. My 6-year-old is a bit tall for his age and the sleeves were much too short. Approx flat measurements: 16” pit to pit 13” shoulders 17” length 11.5” pit to cuff
