I just noticed this a few minutes ago. It's the Stylish Streetwear Jacket Combo chest on the Gentleman Ghost vendor in the HoL: This is on PC. I first noticed it on the vendor preview, so I bought it and switched to it on the Style tab. This toon has the tall Sprite body type. I don't know how I missed it in the character creator, on the test server. Edit: I checked on another toon with the smallest body type, and the result was the same:
Yes. Actually, I did some more testing today. It's the hand styles. Removing the hand style made the chest display properly. Hand/hand blaster styles that would cover the sleeve mesh cause the problem. But only on my Sprite toons. On my Large/tall toon, it displays correctly, even using the hand styles the other two toons wear: I haven't tested the Athletic body type, because I don't have any toons with that body. I'm currently upload a video to YouTube, showing the glitch. I'll update the thread when it's ready.
Edit: Also, I don't know if it makes a difference, but I'm using the Steam version of DCUO, on USPCPS.
At this point, it's become the default appearance of my Mental toon. I took off the emblem, and now she goes around completely torso-less.
