RAM for 27" iMac late 2015

I'd like to order more ram for my 27" iMac (Late 2015), but i'm not sure of the exact specifications I should be looking up for price comparisons.

About my mac says I have: 8 GB 1867 MHz DDR3

Will any ram like that do?

Any suggestions? I'm looking to get 16 more gigs of ram (2, 8 GB sticks).
