This is the sentence I am trying to understand:  
Context: They are talking about recycling

> これはいらなくなった服でお母さんが作ったんだ

I understand the meaning, which would roughly be: My mother made this with
clothes that were not needed. My question is, why is it using that verb
conjugation: いらない+なる=いらなくなった (to become not needed).

Am I missing some nuance in the translation? Why is the sentence written in
this way and would this be incorrect or unnatural?:

> これはいらなかった服でお母さんが作ったんだ

みなさんありがとう！

question
translation nuances
Why is it using いらなくなった instead of いらなかった here?
いらなくなった has nuance that "I needed the clothes before but it became not needed
now."

I think いらなかった don't have the nuance like "I needed the clothes before.".

My nuance is as follows:

> いらなくなった服： used clothes [使]{つか}い[古]{ふる}し  
>
>
> いらなかった服 ： leftover clothes [余]{あま}り[物]{もの}  
>
>
> いらない服 ： unneeded clothes [不要品]{ふようひん}
