If I want to get two 3d objects for the head, will their be any issues?

Could I equip them both?
etc

E.g: Swagtastic gear + Gangster bandanna

No you can't usually, though some people managed to glitch it I'm not sure if that glitch is still active.


Someone might have a more updated answer for you but that's afaik.

You cannot equip two 3D objects but you can with hair styles

Cannot equip two 3D objects of the SAME BODY PART.

Yes what fruitcandy says. You can't wear 2 3d objects on your head, but you could however wear a 3d object on your head, left hand, right hand, and more at the same time.

Closing.
