Need help creating a kids clothing replacer

[N.Gamma]

I have created a replacer for the Squire's uniform.
According to the fallout.esm this is used for the kids Squire's of the BOS.
Ingame the replacer is not displayed on the kids, but they wear the vanilla uniform.
Since the armor I created as a replacer is actually used by adults, I don't know if I need to change anything in the nif to make it work for kids.
Can someone help me please?

Nif is just a mesh, and the difference between adults and children in the game does not rely on it to make a difference. It is not that children's clothing is smaller than adults' size, but rather that the game sets the children's race ratio to 80%.

So if you can find the name and path of the clothes used by Kids Squire's of the BOS, you can directly create a loose file with the same path and name to replace it.
