Yes, I know not everyone does, before you all start shouting that you're too hot and want to wear boots. 
But I do! My skin, which is a pale griege for most of the year, goes a lovely gold in spite of my factor 50. This makes my eyes look bright blue instead of dull grey (are you getting the whole picture here? I basically look like a dementor for most of the year). My muddy brown hair get golden highlights, and I can wear the loose fitting, lightweight, slightly hippy clothes that I feel best in, instead of wrapping myself in lots of woolly layers (I feel the cold badly). I can free my feet in pretty sandals instead of heavy, clumpy shoes. If I can't be arsed with make up - and I increasingly can't - I just stick on a big pair of sunglasses and no-ones any the wiser.
I feel so much more relaxed and me in the summer. I was really born in the wrong climate.
