The photo you’ve linked to here really doesn’t look the same as your toile you showed previously It’s very difficult to assess using some other photo I’m afraid. But I’d say this is not the same issue.
To be able to assess a fitting problem properly it’s important to see the whole thing.
I like to see a full front, full back and side photos, standing normally, to be able to check. There may be drag lines or wrinkles in one place but it doesn’t always mean that is where the problem is. It can be caused somewhere else.
I know it’s frustrating.
Fitting is a whole subject on its own.
I would also suggest that as
@BrendaP said, make sure seam allowances are large. I use a minimum of 1”. Regardless of what the pattern allows, add to it. That way you have plenty to alter the toile. It is not necessary to keep making new toiles. The point of a toile is to check fit, rip, draw or scribble on it, add pieces of fabric in where needed. You do this till you get it to fit. If you keep making new ones you probably won’t know what you’ve done by the time you finish.
Another tip I would suggest that I find absolutely essential in fitting people. Use a ballpoint pen. Draw your waistline across the toile. Draw the hip line across the toile. Draw the back line about midway between the armhole across the back. Draw the bustline across the toile. Draw the centre front and centre back if necessary on the toile. Don’t add a zip or you won’t be able to adjust the centre back. It’s often easier to use a centre front opening to pin yourself in if no one can help. That’s where marking CF and CB is a good idea.
Once the lines are all marked it’s easy to see if the lines are not level, if they tip up, down, sideways. Anything else is just guess work!
