Cloth parenting to rigged (rigify) mesh?

Hello!

I have rigged Metahuman character in Blender 5.2.2 and it works quite well. Put she don’t have clothes. I found one free and nice cloth (Keltainen asu gltf) , but it is made in very strange pose where the sleeves are practically attached to the shirt. Sleeves can separate with L in edit-mode.

My rigify rig rest pose differs so I had to edit pose to follow cloth. After that I edited cloth in edit and sculpt mode and now cloth is in right size.

But how to parent it? Tried to parent it with empty groups (and like others after that in weight mode “transfer weight”). But because rest pose differs it goes wrong.

Is there any easy way to get this parented to rig?
