Zipper installation with a splitting zipper
Hello, not sure if I’m posting this in the right form, but I need help 🙂
I’ve never had this happen before, but when I install my invisible zipper and zip up the back of my dress it splits as I pull the zipper tab up. It does this when it’s on and when it was off (I sewed it twice). I think it’s getting stuck on the midriff piece that connects the skirt and top together, and it might be too bulky, but I’m not sure how to fix this or if I should just install a centered zipper.Â
I did interface the two side seams before I installed the zipper. I also used my bernina invisible zipper foot to sew the zipper in.Â
Thank you!

It’s possible that the added bulk at the intersecting seam is causing just enough stress to keep the teeth from interlocking properly. Especially if you sewed very close to the coil. That is, when there is less strain, as before the zipper was installed, you might not have noticed the tendency of the zipper to pull apart.
Your preparation and sewing steps sound correct. I believe the fault is with the zipper. I think the slide has been damaged or is defective, and as a result it is not effectively locking the nylon coil teeth. Or there is a slight defect, damage, or misalignment to the teeth, with the same result. This is a difficult problem to remedy. Invisible zippers have malleable nylon coils that can become damaged easily. Your best bet is remove the current zipper. A new invisible zipper should solve the issue; be sure to keep the iron off of the teeth coils when you press it, and use a press cloth if you have one.
Yeah, I agree with the previous commentator, that could be right
