I’m mid 40s, and work in a creative type role, so smart/casual is my default. I don’t wear the same actual things for work/not work, but variations on the following:
Cropped wide leg trousers, with slim crew neck or polo neck jumper
As above with tucked in t-shirt, merino or alpaca v-neck cardigan
Mini-ish skirt (I have a few different leather ones) with jumper as above, 100 denier opaque tights
Jeans + blouse, or again, slim jumper, or both of it’s very cold
I also like midi dresses, or midi skirt with tucked in t-shirt - probably more in summer though.
I like Cos for trousers, Whistles or Levi’s (cropped 501s) for jeans, blouses from Zara and Topshop, knitwear Cos, Other Stories, M&S, Whistles. Summery stuff I tend to spend less on because I live in a cold place, but really like Warehouse and Oliver Bonas for dresses.
I wear a lot of leather trainers - black Stan Smiths, Vejas, Continental 80s for work, white Stan Smiths with blue jeans, and I also have gold Nikes. Otherwise flat Chelsea boots, or DM monkey boots.
I have tons of coats/jackets, collected over years, but if I had to cut it right down I would pick (from what’s in my wardrobe):
Big parka with a hood - it rains a lot here! (Whistles)
Leather biker jacket (Whistles)
Oversized denim jacket (Topshop)
Faux fur coat (Zara)
Long cocoon wool coat (Warehouse)
I’m 5ft 6, fairly standard size 10, occasionally a 12 on the bottom
