Her self-named fashion line turns 15 this year, meaning it’s her oldest baby. With her husband of 13 years, Alasdhair Willis, the creative director for British outerwear brand Hunter, she has four children (Miller is 11, Bailey 9, Beckett 8 and Reilly 6). The family splits its time between London and a country pile in Wiltshire, two hours west of the city. “I don’t thrive on being insanely busy,” McCartney says. “But it does come with the territory at the moment, so I’m finding my way through it.” Next month, she unveils her first full ready-to-wear men’s line, complete with accessories like bags, shoes, hats and sunglasses. Menswear is the latest category in a robust catalog for the brand, which was founded in 2001 in a joint venture with fashion conglomerate Kering. Besides womenswear, it includes lingerie, eyewear, a children’s line and athletic apparel with Adidas. Earlier this year, McCartney introduced swimwear and her latest fragrance, Pop. Her womenswear is sold in 77 countries at 852 locations, and this month she opens her 48th store, on Paris’s rue Saint-Honoré. Read more at The Wall Street Journal.
