Since I don't really have any female friends of my own age, I actually ended up offering the post of Matron of Honour to my ex's mother. She is in her fifties and, although she doesn't look old for her age (more like late thirties), I can't really picture her in any of the bridesmaid's dresses I've seen as all the models are (naturally) young, and most bridesmaids in other peoples' wedding pictures (magazines/online) are also usually younger.
We are not going to a specialist store, we're planning to use party/bridal departments in normal clothes stores. I'd like to avoid a skirt & suit if possible - she'll look more like the mother of the bride! She has already said she's not comfortable wearing purple - we have accepted that the dress will probably have to be black with purple accents (our colours are various shades of purple), which will then match the ushers and best man, who are wearing black morning suits and ivory waistcoats with purple pocket squares and cravats.
Did anyone have older bridesmaids/matrons of honour that they could share photos of, or have any suggestions on where to look for pictures?
You may very well be well-bred,
Lots of etiquette in your head -
But there's always some special case,
Time or place to forget etiquette.
