High street fashion retailer Topshop is set to launch a fashion-forward range for expectant mothers.

    The B maternity line, characterised by discreet expandable waistlines, will hit 20 stores in spring.

    It will feature daywear and eveningwear collections and is designed to be 'mixed and matched' with the Topshop mainline.

    Items in the B daywear collection will include skinny-leg jeans, utility pants, motif T-shirt and pleated miniskirts, while the eveningwear collection will include jersey wrap dresses, printed silk shift dresses, chiffon baby doll dresses and ballet cardigans.
