Our office is smart with "smart casual" on a Friday (that means no trainers, no garish logo T-shirts and no blue denim !!)
All the men wear shirt and ties (suits) but the women seem to vary from one end of the scale to the other !! Some wear suits and some wear outfits that really should only be seen on a night out on the town

!!
I myself don't wear suits, but always wear a shirt and skirt or trousers and a smart top.
