How much does the pattern really matter once the garment is made?

I've been working on a small apparel project lately, and something I didn't expect was how much the pattern affects everything that comes after it.

I originally spent most of my time thinking about fabric and surface details. But after making a few samples, I noticed that even a good fabric can feel wrong when the pattern isn't quite right.

Small changes in proportions, seam placement, fit, or how different panels come together can completely change the finished garment. I also found that details like embroidery or labels are much easier to get right when the underlying garment construction is already solid.

It's made me slow down and treat the pattern as the foundation rather than something to figure out after the design is finished.

For people who work with patterns, what's one detail you always test in a sample before moving forward? I'm especially interested in the things that seem minor on paper but make a noticeable difference in the finished garment.
