Trying to represent something in-game that isn't necessarily in the game itself is always a difficult feat. I know this very well because my own character has several aspects about himself that the game doesn't exactly allow for in the character creator.
With that being said, your idea to use the Arachne shirt seems like a solid one. However, if you're anything like me, you'll probably get tired of using the same outfit over and over again ICly. So you might decide to wear an outfit that either covers up the area, or do what I do an emote that the markings are there when you RP. Being that character creators are very specific in what they include, most RPers understand that there may or may not be things that you can properly display on your character.
