Yes I always have some signature items in my wardrobe-at least those like you said are worn the most and on repeat. For more than 28 yrs now I mainly dress for work in an office -so I mastered my preffered silhouttes for each season but formula is usually the same-so think that one is my signature: layering with the 3rd item and NO blue denim other than in my denim jackets.
I layer mostly with
1. blazers-but think more with textures (bouclé, linen, jaquard, plaid) and more sporty than formal
2. puffer vest or a long dramatic gillet (seldom a cardigan )
3. denim jackets (even colors & different weights)-usually worn over some of my S/S dresses.
Bottoms are 3 days a week for skirts(worn exclusive with black sheers or bare legs in summer), 1xweek a pant, 1x a dress.
Skirts:- started with pencils but transitioned to mainly statement patterned(mainly geometric) or textured tubes (but always in neutrals) and/or elevated denim (but NOT the blue ones-so only white, grey or black in different textures for ex. waxed) and some midi or pleated in neutrals.
Pants are usually cigarettes in plaids (various weights and patterns), some wide legs and some white or beige usually crop jeans.
Tops and shells as requested-usually neutral (uni or patterned) only seldom an accent(mainly in summer).
Work dresses are all within the neutral palette of the season -short or long sleeves(knitted or textured for the colds)all to the knee or midi-but occasionaly will do a brighter one in summer.
I don't wear heels anymore (other than some block sandals) my main shoe is a loafer (dark or light-usually patent, or suede) and I love the chunky lug sole nowadays. I also love log booties and a city sneaker.
Outerwear usually is of a somehow dressier kind. Started with wool coats but transitioned to puffers and raincoats-but I always love to have a good trench (I wore a black one for 10 yrs:-) and now I have a new darker beige one which I plan to wear for the comming decade:-)).
Jewelery is also something statement to me. Small studs, a white chunky watch, an artsy cuff (leather or rigid)-sometimes a rigid circle chocker or a statement chunky pendant on a longer leather cord.
And my curent specs.
Oh, and scarves-have a lot(and keep forever:-)) usually bigger ones but wear only with my usually left open outerwear. Bags for work are exclusively light or dark big tote styles(leather, faux leather or straw) no zip, no closures needed as I carry a lot but also drive everywhere. I don't have many bags-and don't change them daily- I wear the bag of the season-for... all the season and more years if possible:-). Sometimes a waistbag for indoors to carry my phone and other gadgets.
