LONDON, July 21 — Hello! magazine reported today that the Phylis dress by Issa London is now available to buy online and in store at UK’s Harvey Nichols.

If that doesn’t ring any bells, you might know it as the navy wrap dress that Kate Middleton wore in 2010, when she and Prince William announced their engagement to the world.

It is arguably one of fashion’s unicorns: Finding one was near-impossible until now.

Issa London and the Knightsbridge-based luxury department store announced the news on Twitter, sharing a photo of the dress alongside the caption: “First seen on the Duchess of Cambridge, @IssaLondon’s Phylis dress tops our wish lists.”

Fashionistas agree that the elegant silk dress, which features a pleated front, flared skirt and waist ties, is universally flattering.

But copying the Duchess of Cambridge’s style won’t come cheap: It’ll set you back £575 (RM3,408) — minus the shipping costs.
