In an ever-changing world, investment pieces – from fine jewellery to beautifully crafted accessories – take priority on our fashion agenda. Much like a Cartier Love bangle, forever bags don't tend to be spontaneous purchases, nor the result of late night browsing and a large glass of Chablis. They’re the styles that you’ve considered and coveted, elegant and enduring – those rare few gems that will chime as much in a decade’s time as they do now. Attention must be paid.
