Where to Get a Suit for a Funeral?

I’m looking for advice on where to get a suit for a funeral in a month. I do not anticipate needing another one for quite some time (whoever does?), so perhaps renting is a good way to go?

Do you have recommendations on where in Seattle to rent a suit, or have you found some online service preferable?

And if you’ve recently been to a funeral, can you describe what’s “typical” in the way of men’s formalwear you’ve seen there?

Thanks for your advice.
