By virtue of its name, bridesMAIDS were traditionally unmarried women.

I think today, people marry at various ages so the traditions get more relaxed. I think most women would prefer to have close female relatives and friends be their bridesmaids, regardless of marital status, than make sure all of them are "maids." Also, it used be unacceptable for a second-time bride to have another big white wedding, and usually only called for one female attendant. Today, women seem to jump at the chance to wear a big white dress again with another (or the same) set of bridesmaids to do it again.
I believe Princess Margaret was the first royal to use exclusively children/teens as bridesmaids because she married at a relatively late age for the time (30) and most of her friends were already married by 1960.
