Definition: A pleat (older plait) is a type of fold formed by doubling fabric back upon itself and securing it in place. It is commonly used in clothing and upholstery to gather a wide piece of fabric to a narrower circumference.
There are different types of pleats you may come across, most popular pleats
are the knife, accordion or the superfine crystal pleats. When pleats are
worked in lightweight fabric, it creates a volume without bulk so the figure
issue is minimized- one of the many reasons why I'm obsessed with pleated
skirts and dresses.
The knife pleats cater for a wide market range, offering versatility and
adaptability across all seasons. It can be updated by layering and altering the
length of the hem which is quite commercial (the high-low hem). Pleats also
work well in metallic's if you want to focus on a more sophisticated look- the
pleated skirt in midi length is a key item for winter season.
