This reminds me of the fake limbs that I had on the back of my convertible.
There was a fake leg with barefoot and fake arm with barehand. I bought them separately.
They come as an arm wearing white shirt and a leg wearing tan pants and barefoot. Since it didn't look real enough, I decided to try something different.
So, I got an old sweatshirt and cut it the length of the arm, then put it on... stapled it.
I also got an old pair of jeans and cut it the length of the leg, then put it on... stapled it.
I even got an old sock (it was a lone sock missing its pair) and an old leather boot (look like Doc Martins).
Finally, I put it up from my trunk and it looked cool.
Unfortunately, I had to deal with 2 different instances... my mom and a guy from my neighborhood.
I was parked at a store one day. My mom came along and saw my car. When she saw the hand and leg sticking out, she almost had an heart attack plus she cried cuz she thought it was me in the trunk.
I was driving away from home one morning and a guy from my neighborhood cut me off, then stopped his car in front of me. He got out and yelled at me demanding that I remove it because he didn't think it was funny. I did remove it, but after he drove away... I put it back.
