My blue 44 AI looks like I’m wearing a paper bag (I found the shoulders to look quite pointy), but I’ve gained quite a bit of weight around the midsection too so that probably throws everything off as well when it’s too tight.
I don’t think I’ve even tried on my black 48 AI but I imagine it’s like the wide-shouldered champion replicas from the early 00’s that everyone loves but just heavier material. As an aside, it looks like the Jerry on mine is situated a little too high and I noticed there is an “A” missing on “athlete” on the jock tag. Saw one on eBay recently with the exact same defects...
From the pro-cut/gamers I’ve seen online the shoulders aren’t as wide as the retail authentics which is why AI is the only person ever who looked good in this style and why I never wear mine out lol. Probably one of the few jerseys where I’d wear a t-shirt underneath.
