Of course it is!
Majority of my wardrobe is Black, white, shades of grey from light grey to slate, some shades of beige, Shade of olive, or mushroom, etc.
I have some purses and shoes that are like Cobalt blue and burnt orange for some color here and there.
I also don't love 'prints'.
The reason i do this is it makes my wardrobe easy to mix and match.
I focus more on 'fit'.
