Whether or not Angelina Jolie is pregnant with twins thanks to fertility treatments, as tabloids reported late last week, at the very least celebrity watchers will get a chance to speculate how far the Oscar winner really is in the motherly way. For her turnout at the World Economic Forum in Davos, Switzerland, this week, Jolie is arriving with nearly a dozen stretchy knit looks custom created for her by St. John. Long a favorite staple of politicos such as Condoleezza Rice and Hillary Clinton, the California fashion brand was only too happy to ensure the star of its latest ad campaign fits the part of U.N. ambassador. The capsule group of straightforward gray and black separates, suits and dresses are based on St. John’s spring collection, designed by Tim Gardner. Could this be the start of St. John Maternity? The company wouldn’t say Monday, but the styles could very well pop up in the brand’s sophomore show at Los Angeles Fashion Week March 23.
