I do quite a different job (I’m a lecturer in digital marketing) but wonder if a variation to your taste of my “work uniform” might work for you? I don’t need to be smart-smart, but I wouldn’t go to work in light wash jeans for example. At this time of year I typically wear really good jeans, with a t-shirt and nice knit/cardigan, then trainers or DM boots. A few recent outfits have been:
Indigo barrel leg Cos jeans, white tee (I like the Uniqlo ones) and mustard &OS cardigan, oxblood DM boots
Leopard print Damson Madder jeans, white tee, cream Urban Outfitters cardigan, brown and burgundy Adidas trainers
Black Abercrombie barrel leg jeans, stripy black and white Cos tee, black v neck Arket cardigan, black DM boots
Coat-wise I have worn a Whistles oversized leather jacket, Arket puffer long coat, and short Cos quilted jacket. I have a couple of pairs of wide leg cords that will be in rotation soon.
In summer I wear a lot of midi dresses, midi skirts and t-shirts, but I really hate wearing tights, so it’s always trousers at this time of year.
