Hi, I would like to help you with the rigging of the clothes that you need, and since you already attached images that explain the situation I don't think I would need too much from you.
I think I could do this work on a day or if there are problems on two, so if you're maybe a little bit interested on my offer just message me so I can try to do the rigging of the clothing and if everything turns out well you could choose my bid.
Oh and I have made some rig fixes of some things before, including clothing. I would be quite pleased if you considered to work with me in the future. So yeah, good luck with the project!
