The Pleat According To Dior

Monsieur Dior says -

 

 For years pleats have been, and will continue to be, a high point of fashion.  I love them because they are feminine, energetic and moving.  They always give a look of simplicity that I like very much.  They are very young.

With pleats you may put the greatest fullness in a dress without making it look bunchy.  They are very slimming and becoming to almost every woman.

They are very versatile, too - you can have box, accordion, unpressed, inverted, and sun-ray pleats - and they all have their uses.
