Work has become somewhat more casual in recent years - so instead of jacket and skirt suits a lot, I am wearing dresses, or my self-styled winter "uniform" is black trousers and a range of different colours of the M&S ribbed polo neck jumper with different necklaces and scarves for further interest. I have decent but comfortable black flat shoes for most days, but a lot of heels for dresses and some formal boots too.
Off work involves a lot of outdoors wear - hiking, sailing, able to get wet or muddy gear, gym gear etc. Almost none of which is wearable in work. Except occasionally 1 pair of hiking shoes (not boots) that can be worn on casual Fridays (which is not a formal thing in our office, but I do it and no one bothers worrying about it). I do wear the same jeans for casual Fridays and off work wear, but there are some jeans that are not smart enough for work.
For work purposes, I still have a long wool winter coat, but mostly use a below knee length Ilse Jacobsen raincoat as I commute by train from a sea-front station, so need protection from wind and rain that is also smart enough.
Non work, I have the long wool coat for formal events, and a couple of different casual jackets for different purposes (just wind, just rain, wind and rain, very cold, ….) and seasons, some of which can be layered. Hiking boots, hiking shoes, deck shoes, sailing boots, waterproof sandals, birkenstocks…
Up to last week, I was still wearing the polo necks as the room I work in faces north at home, so chilled when you sit for hours. But pairing with jeans. (And slippers). This week I have actually relaxed it further, today is warm so a proper summery tshirt and shorts. I need to get some new casual and smart casual items though when the shops reopen.
