Kate MIddleton's Famous Blue Issa Dress Is Now Available in Maternity Style \\ Photo: Getty

The deep blue Issa dress that Kate Middleton wore when she and Prince William announced their engagement sold out in minutes--so now that she's expecting, will the new maternity version do the same brisk business?

The Huffington Post discovered that the royal wrap dress is available on maternity site Blossom Mother & Child for £522, or about $824. The drapey silk and criss-cross styling make it super-flattering for baby bumps, and since it already has the royal seal of approval, we imagine Issa's maternity version will inspire plenty of would-be-Kate-mamas-​to-be.

Would any of you pregnant gals out there wear this dress? Is this Kate-mania overload, or do you dig it?
