First simple steps are to accessorise with a scarf which not only contrast in texture but colour, here's the perfect example from Kiki Taylor (who happens to be good at this kind of thing) with a picture post from her Tumblr blog Christies Closet
Simple day to day style which is quick and easy to achieve.
The next example is from Decoist. This is a really useful example if you want to transport your summer wardrobe into winter as it enables you to layer with sheer garments which makes the outfit pretty and feminine without leaning too much into summer.
Very playful but can be dressed up with a blazer to be made sophisticated.
