oh, but there is science involved...it's not just pretty colours and exclusive price tags. It's about ergonomically designed clothes and all sorts of other factors.. Did you know - for example "In sport, compression clothing has been designed to improve recovery following exercise and training. A similar concept applies to the tight-fitting shirts worn by a number of the teams in the finals of the 2007 World Cup for Rugby Union, with claims of increasing energy levels through transfer of ions to the body". I quite like watching the rugby, hadn't though there was a reason for their tight tops....
