OK - so you have this pattern and it's not so much tight through the hip, but you still get this wrinkle at the back waist. This is the clear indication for the sway-back alteration. What's going on here is that your pelvis is tilting and that means your hips aren't larger, but it still looks like that's what the problem is. I want to ask you to think about this differently, and the alteration you make is therefore different and a much better looking solution than taking up the waist, which is what we all first think is the thing to do. This resource includes an in-depth video and complete step-by-step instructions on how to fit the sway-back, but also what is going on to give you a good background on how to recognize it and how to fit the sway back.
