I love garments with tucks and this tip from Ruth Wyeth Spears and the 1920s delivers tucks in spades! Ruth illustrates a frock and coat, both with one-inch wide tucks. She describes this popular form of trimming as being especially chic on solid-color georgette and chiffon fabric. She also describes the technique of using a gauge (note the typo in the article - the first I've found! - where "gauge" is replaced with "gauze" ;)) to aid in making the tucks.
Doesn't the model rather remind you of Lady Mary from Downton Abbey? Or maybe her mother?
