This is the Lacoste polo shirt L1264AL. It's a model made in Japan. The difference from the classic L1212 is that the color has a heathered look, and there are no side slits. The color is UJF (heather navy, but slightly brighter than the current HAU (indigo blue), with a more subtle heathered effect), and the size is 2 (approximately Japanese size S). Please refer to the fourth image for detailed measurements. I purchased this a few years ago, but it has been stored unopened. The current retail price is 17,600 yen, so don't miss this opportunity.
