I was just watching an old video from a favorite YouTuber, Jennifer L. Scott, who shows some dresses and exclaims, "they just don't wrinkle! So these would be great for a trip."

And it got me to thinking: what are the fabrics or processes that lead to no wrinkling? And which are the ones that definitely wrinkle?

I know I could easily Google this, but I thought people might have personal experience with this. And are you a person who buys with "no wrinkling" in mind, or is that not a factor?
