Serenity In Flight Women's T-Shirt. As long as we never give up, Serenity will fly forever! That's the spirit of this fully authorized and licensed t-shirt by underground artist 11th Hour, one of the first people to turn her considerable talents to the task of promoting Serenity to new fans and a legend among Browncoats. The t-shirt combines both Eastern and Western-influenced design elements into a mandala with our girl Serenity featured prominently in the center. The design also includes the four Chinese characters which represent the phrase "Never Give Up" down the right side. High-quality, machine washable black t-shirt. Order yours today!
