Trousers for me for both sons weddings, both with ceremony and meal/evening in a hotel. The first was a winter wedding where I felt at ease in tailored black trousers, a bright red and black camisole with a matching long red over jacket with black piping. At the brides request I wore a hat, matching red and black. For the late summer wedding I wore light trousers overlaid with floaty chiffon, a matching beaded cami and floaty short jacket. Lots of compliments on both, although I’m pretty sure no other women wore trousers I felt very comfortable. I’m tall and often find dresses are too short for me to feel at ease unless I go for a maxi dress. In my view wear whatever you’re comfortable in, no rules.
