I was asked recently to see if I could offer any advise for a person with one hip different to the other.
I have a problem with altering slacks/pants and jeans in the butt – one hip seems to be a tad higher than the other and causes pulling on the sides or worse yet in the crotch. need help.
My first thought is that you have to fix it at the waist. The jeans for example have a band? I would be pinning just below the band going across the body below the band. This would be on the hip that is smaller. You need to stablise the waist area so it doesn’t pull like you are saying. Stand in front of the mirror and pin like I said with the pins going across the garment so they are parallel to the floor. If you find it hard to pin while on you, pin a bit and then put them on and see what happens. I think this will fix the problem.
Then the amount you have pinned is the amount you take out. So you would unpick the band section where the excess is, and cut away the excess and put the band back on. Just a gathering stitch across the top and ease the fabric in.
If the garment does not have a band, then you may have to shorten at the top on one side only. Again this would be the side where the hip does not stick out as much.
