We learned something from Hayley-Marie Coppin. Hayley-Marie is one of those rare models who enjoys being nude. Men love being naked, and have since we were 3 years old. So we can tend to forget that women often don't share our love of nakedness. Perhaps this is why men originally invented pin up photography: so we could experience the sight of a woman who loved being naked too. These days, pin up is enjoying a modest revival: many models and photographers are revisiting the classic settings and poses. But there is something missing from the modern pin up re-makes. It's something Hayley-Marie exudes in her photos, especially when she is naked. And when we look at our own pics of her we learn why pin up was so popular in its day. The women in those photos experienced joy. They were not just pretending to be in ecstasy feeling the sea air on their naked bodies, they truly loved it! They were not just posing, they really were running along the beach completely nude. As silly as some of those old pin up photos were, whatever crazy things the ladies in those photos were doing - those models really meant it! We learned this from Hayley-Marie, who to this day is the only model who can do pin up and make us believe it. She makes us believe it is truly wonderful to pick apples stark naked. And there is no beauty quite like it. It's the beauty of someone enjoying life, the way small children do, or kittens. In fact, seeing Hayley-Marie smile is almost as much fun as being naked ourselves.
