Texture Looping

henloo, I actually need a little of help. I genuinely started the study on cutting full body to top / bottom yesterday and I did not expected this kind of looping and I'm pretty curious with what I'm missing. I also been trying to read whatever tutorial gave me about this issue and it said about UV mapping and even tried to well what it said... cutting the part and move it to the body map (if I recall it they named it sims 4 template) and baked it to make sure the texture stayed in place. still no luck. this the picture I talk about :

this the picture of the dress without the texture and after the texture

then this is the one with the mapping

so now, I'm pretty much lost... like what step do I miss to cause this, any step by step help is so appreciated! I would love to know how to get this one fixed because pulling the what it's called? the line on the mapping up to the body seems too far of a 'push'

in case the material is needed is on my drive : drive.google.com/drive/folders/1EHcGP91Iw3vu3FQ9TdNNZw-vz2MA0Dtc?usp=drive_link

hopefully my thread is clear enough, I'm sorry if I it's not clear enough, but any help is appreciated ^^
