Seersucker is different from plisse. Seersucker is woven puckers;
plisse is an embossed fabric, and these days stays permanent if it has
synthetic fibers in it. Seersucker is also a bit heavier.

The fabric I remember with tiny roses was dimity, but dimity doesn't
have puckers--it has solid woven stripes next to sheer stripes, with
the tiny roses printed.
