A nice addition would be a complementary shrug to go with it. They're very "in style" and not expensive. It would tone down the contrast between the dress and your upper arm tattoos (not that you should hide them completely).
I just grabbed a few pics to show you how they go with cute short sleeved dresses. Stay away from red, or anything too bright that would clash. Try a sheer/see-through grey or black to see if you like the look first.
