Do you want a buttoned collared shirt or a pull-over collared shirt? There are a few stores in Philipsburg that sell collared shirts. There is one that sells Jimmy Buffett shirts as well as a few other brands with the same idea in mind. All buttoned shirts and great for beach or evening wear. Only problem is I don't remember the name of it. I think it is close to, or very close to and across from, the bamboo store which is on the end of the Front Street closest to the Greenhouse Restaurant.
