A stylish new collection of maternity fashions designed in collaboration with leading US supermodel Cindy Crawford will go on sale at Bloomingdale's next week.

Called "babystyle Maternity," the $248 collection includes cotton/lycra tee, two-way stretch twill slim skirt and bootleg pant, and stretch poplin shirt, slim skirt, long-sleeved top, easy pant and tank dress in both black or a white/khaki combination.

It will be launched at Bloomingdale's flagship New York store next Tuesday by Ms Crawford who got involved in its design two years ago after finding it a challenge to find fashionable maternity clothes.

"The babystyle Maternity Collection is a modern, solution-based approach to dressing, ideal for pregnant women who don't want to spend a fortune on new clothing but who still want to look and feel stylish," said babystyle's founder & CEO Laurie McCartney.

Ms Crawford added: "There are enough things to worry about when you are pregnant, what to wear should not be one of them."
