BACK TO THE FUTURE 2 , Marty McFly Jacket

HellOO,
Like many of you, I "tried" to "improve" a jacket bought in China (B & MJ)
Color a little too orange for my taste .... and the length and finishes ..... I had to change the look ...!
I did you learn anything .... saying that it takes time, but most of all patience .... and a lot of desire ....
Initially, I painted the jacket "in primer, then black."
I shortened the jacket at least 2 inches.
A little sewing, gluing ...
Then I painted primer ... then red color "burgundy", a non-slip floor mat for car trunk.
A little cutting, gluing ...
To this we add some electronics (MP3 + Mini Speakers).

It remains, however, still some finishing touches to complete ....... but overall, it is lmost complete.

Thank you.

Where do you get the cuffs and the waistband for the jacket?

Hello,
Sorry for not responding sooner, I do not often go on RPF ...
That said, to answer your question, I used part of an office chair: what I call the "bellows / accordion" that surrounds the metal. Metal part that goes from the seat backrest.
And to make the entire jacket: sleeves and bottom ends of the jacket: I bought four office chairs. Simply because I have not found a way to buy only this part of the internet.

Hi, Can you describe better the process? Materials list specific. Please I interesting for your jacket. Look amazing
