One of the things I've learned with Lacoste is that often the shirts you see the pros wearing generally aren't available to the public. There was a red polo Llodra wore earlier in the year that was in demand with some posters here but we never managed to find someone selling them.
If you haven't tried euro sites yet then take a look, I got my black poly lacoste cap through one(no one in the US sells em as far as i know). Oh and if you browse the lacoste shop website, another poster gave me a useful tip. Not all of the tennis shirts are found in their tennis section, try searching for "super dry" or "color block".
