As a national sponsor of Go Red for Women, Macy’s is encouraging all to wear red on Friday, National Wear Red Day.

Customers wearing red or purchasing a Red Dress pin will receive a discount of up to 20 percent, with Macy’s donating 100 percent of all Red Dress pin sales to the American Heart Association.

The pins will be on sale at all Macy’s through Valentine’s Day, Feb. 14.

In addition, Macy’s is featuring three red dresses in support of Go Red for Women, in which 10 percent of the purchase price of each dress will benefit the heart association. The dresses will be available at select locations and at Macys.com.

The retailer has collaborated with the heart association for a decade in promoting women’s heart health and raising awareness of heart disease as the No. 1 killer of women.
