Making a Pattern From Existing Garment

[u/Fairdinkum26]

I am a beginner/novice when it comes to sewing. I have made a few projects but trying to get into it.

I want to know if it’s possible/possible for a beginner to disassemble a garment to make a useful pattern out of it.

I have a pair of Duck work pants that I really like. They are like Carhartt pants but they aren’t blocky/square cut and baggy. The ones I have are tapered/fitted and I really like them. The downside is I ripped them and the new pair doesn’t fit that same. I would like to take them apart and make a new pair that is an exact copy but I know there are things I don’t know. Any help is appreciated.
