Send in the clones!

Wannabe princesses desperate to emulate Kate Middleton's style can now score bargain replicas of her blue Issa engagement dress, the Mirror reports.

While the original wrap dress worn by the brunette Brit as she announced her engagement to Prince William has already sold out, UK supermarket Tesco and its in-house F&F label have created a £16 ($25) version with shorter sleeves, according to the paper.

"Many women will want a replica," Tesco's Jan Marchant told the paper.

"We expect it to sell out fast."

And with good reason. Along with the Issa feeding frenzy, Middleton's sapphire and diamond engagement ring has already spawned a wave of replicas thanks to public demand.

Sheesh. This girl's like a one-woman economic stimulus package.

And while we're bracing ourselves for an onslaught of Middleton lookalikes, the future royal has already been parodied by a blue dress-clad Anne Hathaway on "Saturday Night Live" over the weekend.

This is going to be one long engagement.

Meanwhile, bookies are betting on Phillipa Lepley to design Middleton's dress.
