I’m a lecturer in a creative subject. I’ve been WFH since last March but when I do go to actual work I wear variations on:
Wide-leg cropped trousers/culottes, with slim knitwear, or fitted tops (often striped)
Mini-ish a-lime skirts, again with fitted knitwear, and 100 denier opaque tights
Midi dresses
Straight leg black jeans (Levi’s 501 crops) with blouses tucked in
Footwear is often trainers (black Stan Smiths, Vejas, or Continental 80s), but can be chunky brogues, or DM monkey boots.
I like Cos for trousers, skirts often Whistles, knitwear Cos/Arket/Other Stories, dresses Zara, Topshop, Warehouse, blouses mainly Zara.
I always wear red lipstick, and my hair is (usually) cut every five weeks so it always looks sharp.
My take on it would be to figure out a “look” you like, then own it - I often buy the same thing in multiple colours if I like it. I’m quite hippy with a small waist so I always do this with trousers!
