Another Fabric for Same Design

I tried another fabric for same design today. result? DIFFERENT! May be, it was combo fabric and interfacing. I used not suitable fabric and combined with ‘wrong’ interfacing. Today, I used another cotton fabric. Still thin but not flowing/fall. It’s not easily wrinkle. I also used different interfacing. I used light-stiff interfacing, used for collar. Way better or may be i should say, it’s just normally i used to make.
