How do you differentiate spring vs autumn style?

As we're about to transition into spring here...

I think a lot of us find the winter into spring transition more difficult to navigate than the autumn to winter transition. My question is, what do you do to make your spring style different than your autumn/winter style?

Both autumn and spring are transitional seasons so that usually means layers and lighter materials. Do you have separate pieces that you bring out only at specific times of year?

I personally find I have loads of autumnal things in deeper colours and materials like corduroy, that don't seem fitting in the spring. However, I'm not ready to ditch all the woollen things anytime soon, and my summer stuff is way too lightweight to start wearing yet.

Do people really have separate spring jumpers and cardigans separate from autumn stuff? Or are you happy to wear the same things through the year?
