Can we stop getting just one swatch for certain clothing?

Why? So it can be reused in a later pack with a different swatch. Sold back to you later with a different color, etc. It's been done (the reuse assets practice) over and over in the life of TS4. Or released to the masses (who don't have a pack) for free in a basegame patch. But in their defense not all meshes work well with any color or pattern. You will see flaws in the mesh and or at the seams etc., or the over saturation etc. But I'm going with the first reason I stated.
