While you're pretty much allowed to wear any avatar in the sim, please avoid using any incredibly large, small or other avatars that obscure the hitbox. Giant robots and tiny dinosaur avatars and such are not permitted. As for objects obscuring or shielding the avatar such as shields and invisiprims, those will result in a quick eject followed by a ban if not removed. Only shield allowed is the one sold with the Black Ops Raging Bull, and only while being used with that weapon.

As for clothing, we're not too concerned with looks, however any human avatars should have coverings over the private areas, whether your skin has anything there or not. Bits (private parts) are not allowed, detach any xcite or similar objects before coming into the sim. Anthro/animal avatars without clothes are fine as long as the skin does not show any private areas, otherwise coverings are required.
