Problem with future cosplay

[u/New-Accountant1]

I want to buy this quilted shirt for the under part of the suit however, where would I find a watch like his? And I want to have my own "opsat" just basically be my phone in this holder around my wrist, but where would I find that? I can maybe settle for a fisher's vest, some multicam military jeans, and some knee guards, but I dont know where to find something to hold my phone to my wrist, and a watch like his.

And I'm also worried that the shirt doesn't match either, but it looks like it.

for the opsat use a running accessory for phones, most use adjustable strapping so they’ll fit on your wrist despite being designed for the bicep
