Honestly, Gitman are my favourite shirts hands down. I've owned everything from Ben Sherman to vintage Brooks "Makers" shirts (which have cache with many current "Ivy-ist") and the Gitman Bros Vintage just work for me. They are quite dear if purchased new, but I have found at least 7 through eBay for less than a new shirt from Uniqlo.
Just takes a bit of patience 🤓
The trick with Gitman Vintage is to wait for the sales - shirts that normally hit £160 will go down to a ton - BEST shirts out there for me at the moment .
