This month of May, Allure magazine has covered a list of icons and their true signatures. No need for introduction, these women of the past (and some present) continue to influence our present and most likely, our future. This “Beauty By Numbers” tid-bit put together by Kate Sullivan, Associate Editor, should be an inspiration to all who dream to be icons. So here it is, from Allure, to me, to you.

Icons
