If you have booked a professional hair and make-up artist for yourself and the wedding party, they should have no trouble dealing with the mother-of the-bride/ groom too. The best option is to let her have a trial run, which I offer all my brides' mums. There is a knack to doing make-up on mature skin think: lifting and not too much sparkle/glitter, not too much powder and don't forget to colour those lips! Try to have an adult hairstyle as well, a nice blow dry or chic up do is much classier than ringlets hanging around your shoulders.
