So my cousin grabbed a shirt for me on his way home on Friday night - a white shirt with black and purple check pattern. Apparently, most of the shirts are check patterns in either a purple/black or blue/dark blue pattern. The purple/black was all that was left in size 16 - RLPL tends to do this color combo quite a bit so I've seen this before. I'll give it a try for $29.99.
For what its worth, these are not in the high-end RL shop at Woodbury. They're in a rack in a corner of the main, larger RL store that usually sells all of the short, polos, etc.
