   It sounds like you need a little more room across the back.  I believe the fabric is lifting until there is enough room.  I also have to have more room across the back and I often widen the back maybe half an inch added to each shoulder seam and make a small dart or pleat along the shoulder seam on the back.  (slit the pattern top to bottom half way along the shoulder seam.)    You don't want to add it to the center as this will affect the size of the neckline and mess up any collar application.

   Hello.

   I sometimes see this problem with various people when they are wearing a garment with a collar such as a jacket or a shirt. To remove the wrinkle you need to undo the collar seam and allow the fabric from the back to rise into the collar. When the rinkle has gone, you can simply attach the collar back up again and you should have a wrinklr free back.

   Good luck and happy sewing.

   Michael's comment will solve the problem on an already made garment but will not solve your problem on every pattern that you use before you cut it out.  Imagine this - cut your offending blouse or shirt from hem to collar seam at center back and guess what will happen - it will lie flat because  it will separate enough to hang properly.   The separating means you need more fabric across your back.

   I tried both suggestions, and all it takes is about an half inch increase in the back and the collar wrinkle goes away.  Thanks.
