Help! Could we connect the target tracker to try on cloth?

Hi there, I was working on a project that has a requirement for :

“When I scan the picture that is embedded in my real-life outfit, it activates digital cloth/clothing try-on feature”

just try it by parenting the occluded mesh and 3d cloth mesh to the target tracker, somehow it works. but the scale of digital clothing is too small. and not fitting my body

any suggestion appriciate!
