What is the best way to connect 1 or 2 DVI monitors to the 2015 Retina MacBook? (What adapters do I need?)

I Am trying to connect my 2015 retina MacBook to either one or two DVI displays. The displays have VGA ports as well but I would prefer to use the DVI ports. I already have the Apple Digital AV Adapter (USB-C to HDMI/USB/Charge). Thanks!
