Do you know where to get a sweater Abby on NCIS wore?

In several episodes, Abby, on NCIS, wore a black sweater with a ribcage and are bones knitted into the design. On the back is a red rectangle/bar. I've been looking for the same or similar ever since seeing it. Any idea where I might find one?|||Maybe ebay? But other than that I don't know where you would find something like that besides Hot Topic.
