The last wedding I attended was 2 years ago in England. It was a rather formal affair. The groom was in his newly hard earned Marine full dress uniform, his best man in a kilt. I was one of only two female family members not wearing a hat. (And I was okay with that, since hats do not suit me at all.)
It has not gone unnoticed that people over on this side of the pond tend to dress much more casually for any event. There was a time when I had Sunday best clothes and office suits. Since I no longer work in an office and don't attend church, I have little use for those Sunday best clothes. For our family dinners, we all wear clean clothes, mostly of a semi casual type. My brother now owns a tux from a formal wear shop that is going out of business, so maybe we'll have to have at least one cocktail party a year for his tux to have an outing.
My niece loves to dress up. A particular favourite era for her is 50s attire, so she looked perfectly natural in her ivory pink wedding gown with a strand of pearls. Her partner, who does not like to dress up, looked very elegant in a black suit with pink tie and shirt.
It was a garden wedding, held late morning. Still, on looking at the gathering, a friend and I
Really, would it kill you to wear some well fitted clothes that bring out the best of your figure, that shows you have a little style and that you care enough about the people you are with to make an effort to look pleasing to the eye??
Even Gus didn't make a fuss when this get up was foisted on him!
