Pentland Chaussures, owner of the global footwear licence for Lacoste, appointed Green Room Retail after a three-way pitch.
The agency will now create point-of-purchase installations, window displays and other promotional materials promoting the Lacoste tennis range.
They will appear in Lacoste stores and concessions throughout Europe by the end of the year.
Green Room Retail also works for brands including Levi's, Nike, Omega, Nokia and Umbro.
The Lacoste legend was born in 1927, when tennis star René Lacoste revolutionised mens' fashion replacing the classical woven fabric, long-sleeved and starched shirts on the courts with what has now become the classic Lacoste polo shirt.
