Vintage T-Shirt Forum & Community Authentication Appraisals

HI guys ,
this is a Iron Maiden camo t-shirt, I think it's real and I had it for a while. I paid 600 US dollars. So I would like more info about this t-shirt. I saw other t-shirts and they weren't cut down the sides. I'm not sure if it was cut by the factory or if the owner cut it themselves?
I would be happy for any detail you can tell me about this.
Thank you so much

good q. I dont think the side seam was done by the wearer - unless you can tell its an amateur job? but not sure why someone would. Some shirts are manufactured that way. Ive noticed the torsos of the ones that do tend to become more mishaped over time. Would be interesting to hear from a t shirt manufacturer as to the difference but assuming its a less advanced way to manufacture.

Thank you so much for the advice and details about this t-shirt.
Sometimes you pay a lot of money so I wanted to know clearly about it.
