This is how my people dress/ do things, also. I would simply buy a decent looking western shirt from Sheplers online and wear with jeans-- since no cowboy boots I imagine, can prob do with tan chukka boots.
Going to be warm & humid today, but suited up for office and event after work
Gray MTM sartorio suit
RL tie bar
Omega gmt seamaster
Brown Lobb captoes
Clean white shirt
Edit-- had to spend night in the city, gray suit day two. Love this suit/ Lovin the shoulders on this one, happy I bought it
Meh...I think you might be too traditional for me, Brit sensibilities but not enough Italian 😀 These are my most comfortable fits/ cuts that both lengthen my stubby legs and have a nice close to the body fit on the sides/ under arms.
