I'm going to a funeral tomorrow and they said to wear the clothes that's more comfortable. What should I wear that's appropriate?
Those funeral directions are vague. No wonder you are on here. Wear black. Wear casual. Comfortable = casual.
Slacks and a t-shirt with no words.
a striped shirt, Khaki pants, and sneakers.
You're probably going to be walking a ways then! Wear like work casual, nice polo or button down shirt, tucked in, jeans or khakis that fit with a belt, sneakers!
