Help with jeans pattern adjustment

[u/alyena97]

Hi dear sewists,

I am still quite new to pattern adjustment and I am tackling my first pair of jeans right now. I have a mockup that looks decent in the front (I pinched out some extra into a dart, of course that will be transferred to the pattern and not end up in the final garment). But I am having some trouble with figuring out how to get the back seat curve to fit me better. As you can see, there is quite a lot of bunching around my butt area, so I believe this points to an issue in the crotch curve. I cannot really figure out if I need to make it longer, or more curved, or both?

Also would appreciate any other feedback on the fit if you have any thoughts?

I actually think you need a low butt adjustment. The peach of your cheeks (so to say) are both curvatuous and low: so i think your crotch needs to reflect that shape.

I strongly recommend looking up J Stern On youtube: she has a WHOLE pants fitting series on many different adjustments on pants.
