Kate Middleton in her Ralph Lauren Black Label Cashmere Sweater ($400, Net-A-Porter)
We are officially in shock – Kate Middleton’s exact Ralph Lauren purple cashmere sweater ($400) is still available at Net-A-Porter. Back in July, we told you about a little thing we like to call “The Kate Middleton Effect,” which is what happens after she wears something in public: it sells out immediately – but not this time. For whatever reason – maybe it’s her tennis shoes (above, left – ew!) or the 90-degree heat – her cashmere Ralph Lauren sweater has yet to sell out. But we’re betting that once the temperatures start to cool, this sweater will be off the shelves before you can say “duchess” – so scoop up Kate’s sweater before it too sells out.
