The black Six-Way dress has adjustable straps, so that the dress can be worn with modest cap sleeves by day, and as a bandeau, halter-neck or even one-shouldered by night.
And it will even prove useful after the baby is born, as the waist provides support for a post-pregnancy stomach, while the adjustable neckline makes it suitable for breast-feeding.
It can be worn in six different ways so no one would know that you are wearing the same dress every time, making it a must for every pregnant woman's wardrobe.
It can be a casual dress or an elegant gown, has adjustable straps so it can be worn strapless, as a halter-neck, one-shouldered, with cross-over straps or as a capped sleeve dress.
The ankle-length garment is made from polyester and elastane, so it is conveniently machine-washable. It also has essential built-in bust support and can be worn by breast-feeding mothers.
"It is a must-have for holidays. Think of all the extra room you will have in your suitcase," Joanne Garrett quoted Cecily Plum as saying.
The dress is available for 79 pounds at cecilyplum.com
