I wear (cheaper brands though) a sort of mix and match "uniform" am 5ft 10 and a top heavy 16/18
Navy, black, grey print skirts
Black wide leg trousers (M&S, heavy and hang well)
Maroon, dark green, grey blouses
Tops in green floral, navy, black
Navy cardigan, black cardigan
Black blazer, printed blazer
Black ankle boots, black t bar heels, nude t bar heels, black loafers
Black or nude tights
Black bag, tan bag
Then I have dresses (too many!) in various colours and prints including grey, black, striped, small floral prints
I can go to the wardrobe and pull out a black skirt, green blouse, black blazer, tights and shoes and be done!
