Should I wear ASU to Arlington Funeral?

I’m attending my grandfather’s funeral at Arlington In a few weeks. Should I wear my ASU? I’m a PFC with 16months TIS. I don’t want any attention, but not sure if it would be more appropriate to wear given the location. I wouldn’t wear to a civilian funeral, but unsure what to do. My grandpa has 43 years serving the Marines and I want to honor him properly. Thank you.
