Inconsistent Layer Width on Curved Surfaces

[Whimand]

I’m fairly new to Simplify3D and 3D printing. I’m currently printing some organic shapes with gentle curves, and I’ve noticed that the outer walls sometimes look uneven, like the layer width is slightly inconsistent on those rounded sections. It’s especially visible on glossy PLA prints.

I’m using a 0.4mm nozzle, 0.2mm layer height, and 2 perimeters. Outer wall speed is set lower already.

Could this be due to the model geometry, or are there settings I should tweak to improve this?

Could you attach a factory file so we can take a look at it?
