  Look up 'shadow terminator artifact' in the forum for details. It can happen in Iray given a certain set of circumstances. The threads run down what can cause it, and how to (attempt a) fix.

  Thank you for your quick response Tobor. I searched around a bit but can't really find a solution.

  Also, I'm wondering why this is suddenly a problem. It only happens on a few clothes, not on skin or anything else. And I have renders from a few days ago, with the same clothes and materials applied where the shadows are smooth.

  I'm so upset about this.

  If that's the case...is the SubDivison/mesh resolution the same?

  Are the items in the same location (have they been moved, from say, the 0,0,0 default load location)?

  Is the lighting the same/similar?

  The items are all default, so the  SubDivison/mesh resolution should be the same, I think?

  I did a lot of testing, so I moved them around a lot and changed the lighting as well.

  It's silky smooth on skin and the jeans. And as you can see it's absolutely terrible on "Top & Shorts"  by RainbowLight.

  Thank you for your help mjc1016!
