I would not say that all my shirts and trousers are black but they are mostly in dark shades eg khakis. I have a few colourful shirts that I tender to wear infrequently. Dark colours don't need washing that often!
The main colors I have are black and white.. but i do have clothing of almost every other color as well but just not many of them.. I dont see myself as a very colorful person.
my closet used to be all black, if find this colour is so easy to match with anything. but now I find it very boring looking
I have every colour in my closet. I actually have my clothes colour-sorted. Red-Orange-Yellow-Green-Blue-Purple-Pink-Black-White ... it's wonderful
i have a variety of colours, i find colours bring out the mood in a person and changes the look in some ways
