Well, the best time is circa one year before the wedding. You will have enough time to prepare everything without stress and rushing. But it doesn't meant that it's not possible to make it in 4 months.

Wedding rings are something for the rest of your life so you should choose very carefully. By the time fingers are becoming thicker (mainly ladies).

The purpose of accompanying the bride and groom is a kind of symbolic entry into the state of those who are already married. It must be accompanied by a marriend person older but it doesn't have to be necessarily a relative of the bride/ groom.
