Small text reads: "The context of the word “rocks” above is that of the slang definition meaning, “To use, to make due with, usually to great effect." Or, as a practical example, "I'm gonna rock those jeans hard in the club tonight." In the case of this shirt you're looking at, what is being “rocked” is Shipley & Halmos, a NYC-based clothing brand that produces fine wares for men. (This t-shirt is not really the best example.) Nevertheless—it's limited edition—and that should count for something." 100% cotton and includes the exclusive "Made in S&H" woven label. Machine washable and made in America. Limited Edition of 30 produced.
