I spent a couple of days in the Californian desert to see the land art by Desert X. This one, by artist Claudia Comte, is called Curves. I felt like wearing a practical and comfortable outfit. Wearing monochrome is always a way to make a point. This time, I chose white. It’s a colour I often wear. It brings a general freshness, and is invariably elegant. It works well when worn all over, and is one of my favourite hues alongside navy blue and beige.
