Pleats, pin tucks or growth plate?

I am putting pin tucks on the bodice of my doll dress, but had chosen to machine sew them instead of hand stitch them. I also chose to reverse them, not sure what its called, but would think it would be called a growth plate of some sort? Top photo, doesnt she look like a bride from the old pictures? I think so.

 Hope everyone is doing well, and are happy that summer is almost over,
 Many Hugs,
