I don't wear the same clothes all year round.
Spring/summer clothes, to me, should be colourful, have different prints, be made of different fabrics. I would not wear a sundress made of silk/cotton mix in autumn with tights underneath and a coat on top. I like the seasons to feel different from each other.
In winter, I wear black, grey, maroon, blue, navy, white. In autumn I may wear more oranges, reds and browns as well as the above. But I like wearing pretty, softer colours in spring, plus florals, and then in summer it's corals, bright blues, jewel colours, etc. But I live in the South so even though the weather's been fairly crap, it's not actually cold.
