Fact of the week
In 1923, French tennis player René Lacoste was promised a crocodile leather suitcase by his captain if he won his next match. He lost the match but won the nickname "the crocodile" which he had sown onto his tennis attire. Ten years later he launched the first polo shirt and Lacoste, the first brand to feature a logo on its clothing.
