It depends, I threw on a button up, some Khakis and black K-Swiss classics to my cuzzin's funeral and felt like I was overdressed. nikkas had airbrushed shirts and all types of hood shyt.
This was a funeral on some gang shyt. My nikkas was imn the casket with a blue Khaki suit, all his jewelry and his Compton hat.
I miss that dude.

Anyway, you should be good with the jeans and boots. Get an airbrushed RIP shirt and they gone love.
