Is it raining? Wear a hat. Too much sun? Wear a bigger hat. Not to mention how easily it fixes a bad hairday. Conclusion: Buy a hat.
Wearing a hat is a statement on it own, so tone down the rest of your look. I chose a neutral white skirt and added other elements in approximately the same colour. This hat gives also a little bit of a boho vibe so these borrowed shoes correspond perfectly with that style.
