I removed all the supports for my mannequin after I had trouble displaying my DD suit on it. Short of cutting a hole in the left boot and two holes in the jacket I didnt have many options.
I just got a 6 foot metal bar and attached a bracket to the back of the neck of the mannequin. The top of the pole rests on the bracket, I then attached the bottom of the bar to the base I knocked together for it. Worked better than I thought it would.
So I'm fine as long as nothing I put on it wants to wear a necklace :lol
