Polo shirt---a new style casual top
the short, cuffed sleeves solved the tendency of long sleeves to roll down
the soft collar could be loosened easily by unbuttoning the placket
the piqué collar could be worn upturned to protect the neck from the sun
the jersey knit piqué cotton breathed and was more durable.
the "tennis tail" prevented the shirt from pulling out of the wearer's trousers or shorts
In 1933, after retiring from professional tennis, Lacoste teamed up with André Gillier, a friend who was a clothing merchandiser, to market that shirt in Europe and North America. Together, they formed the company Chemise Lacoste, and began selling their shirts, which included the small embroidered crocodile logo on the left breast.
