Armani Junior Kids Wool Crewneck Knit Sweater Size 8

Check measurements pictured! I could not find a size chart to see what the Roman numeral 5 meant for size because this is definitely not a kids size 5. I’m 5’1” and it’s kind of like an XS on me. Comparing other listing measurements from this brand I’m guessing it’s a boys size 8, or maybe 10. Smoke free home. In excellent condition. G02
