The pink two piece has a nice amount of stretch.  However, it is meant to be fitted.  It has a drawstring and zippiers on the legs.  Zippers can be worn open for a little flair.  It fits true to size.  If you don’t like a close fit I would say go up a nice.  Material soft which makes it really comfortable to lunch or errands.  Through on some jewelry and heels for a more dressy look.
