Dior Addict Lip Glow (£29.50) is one of the chicest handbag companions you'll ever own and it's also a total delight to use. The shea butter-packed balm provides day-long hydration to keep dry lips at bay. Even better, there are plenty of shades to choose from, including universal, which provides clear, glossy hydration to something with a little more pigment like plum or mahogany.
