Mal wears this at the end of Serenity:

Some more promo pics:
And some screencaps:
The shirt was at the Propstore for a bit:
He wears this costume with the same suspenders that he wears with his Heist and his Maidenhead costumes. In fact, this particular costume is extremely close to the Maidenhead costume, but the differences are many. Some of the differences include the color of shirt, the buttons on the shirt, and the color and style of pants he wears. They are very subtle differences, but they are confused often.
