My "uniform" is made up of some a few pairs of skinny jeans in 4 different colors. I pair them with a V neck Amazon Essentials tshirt. I buy them in packs (different colors and some duplicates) and I know I like the fit of them. (This in 5 colors: https://www.amazon.com/dp/B07767BHGY/ref=cm_sw_r_cp_apa_i_jNE8CbHZDT05E. I also sleep in them. LOVE them!)
Then I have a blazer, a few scarves & necklaces and a couple duster cardigans I mix and match everything with.
I'm not a hardcore minimalist but having this base to work with makes like soooo much easier!!
