It seems Lacoste and Izod have split, no longer the same company. Izod still makes the alligator stuff. Lacoste has that shield logo.
I've gone back to the alligator. I like the alligator better and have started wearing them again after 20 years of forsaking them for the Ralph Lauren stuff I like better. For some reason, this summer the colors of Izod were much better; particularly that aqua shirt Turtle was wearing in Entourage. Tried for ages to find it but every store was sold out of that particular color. I'm not a fashion horse by any means but that was a great color. Grrr.
