Even though it's warm in Florida most of the year, I still respond the change of seasons by changing my wardrobe. Solid black and gray tops have to move over for (me) ivory and navy, and my favorite, ivory/navy stripes. For you, maybe it's bright tops in turquoise or teal, yellow or coral. For skirts I still prefer black, navy, and denim with perhaps a wild-card print from Anthropologie to mix it up. I don't often wear trousers, but it's a lovely time for linen pants, with hems all the way to the shoe-line please. All the stores carry crops, but --- for my eye, nothing adds years quicker than "flood pants"!
