Remember back in 2010 when the Duchess of Cambridge's navy blue Issa wrap dress - worn to the announcement of her engagement to Prince William at St James's Palace - caused a shopping frenzy, sparking the beginning of the Copy Kate effect?
Well, we could be about to have a case of deja vu, as Harvey Nichols has re-issued the iconic dress.
Announcing via Twitter that the Phylis dress is back, Harvey Nichols wrote: "First seen on the Duchess of Cambridge, @IssaLondon's Phylis dress tops our wish lists."
The wrap dress checks in at £575 and is being stocked in sizes 8-14.
Kate's ability to sell out almost anything she wears shows no signs of stopping, and even Prince George has followed in her footsteps, sparking his own royal-inspired collection for posh baby brand, Trotters. But there's no doubt Kate fans will want their hands on the piece that started it all.
Go, go, go if you want a Phylis dress of your own - we're sure it won't be long before it sells out for a second time.
