Leading women's lingerie manufacturer Wacoal Corp on Thursday unveiled plans for a new line of underwear for middle-aged women that it claims will also give them a range of health benefits.

The company said its new Daily Wellness line will include garments such as blood circulation stimulation stockings. The collection will be sold in department stores from next spring and in up to 50 Daily Wellness stores by 2005 as Wacoal targets annual sales of $12.1m.
