Selling my older 87 Dallas Mavericks tracksuit type button up shirt. I say warm-up tracksuit shirt because whenever you see the players warming up they wear their team, what looks like a tracksuit to me, warm-up suits and this is an older style Mavericks shirt and the size says Medium 12/14 but it really fits more like a small or extra small but it's really dope. True classic says Dallas 87 down on the lower tag that says the size and Nike on it, get it while you can will not last long!!
