I was advised that this shirt was legit. What would you price it at?

I saw a two different posts both on white. One was approximately $200 and the other was $3,000.00??
Asking for help
Thanks!

I need help figuring out if this shirt is legit and if so, what the value is.
Measurements are pit to pit 24 inches and the length is 32 1/2 inches.
Thanks for any help!
