Mine is a set with a diamond wedding band that wraps around the solitaire on the engagement band. I wear the wedding band below the engagement band. On the day of the wedding, I wore my engagement band on my left hand. When it came time to put on the wedding band, DH put it on top of my engagement band (upside down from how I wear it today). After the ceremony I turned it the right way. I didn't feel like wearing it on the right hand and trying to switch them during the ceremony, and I certainly didn't trust the best man to hang onto it!
