Kate Middleton"s Engagement Issa Dress Is Now Available In Maternity Sizes ...

Since Kate Middleton wore that now-iconic Issa dress in her engagement photos back in 2010, we’ve seen the original shipment sell out within hours, the second shipment hit Net-a-Porter and a fake version retail for a mere $25 — not bad for a look originally paired with Princess Diana’s former engagement ring.

But now that it’s 2013 and there’s a royal baby on the way, the latest iteration of Issa’s famous frock comes in — what else? — maternity sizes.

Thanks to the keen eye of our lovely Twitter pal @britishroyals, we’ve just come across one of the first royal pregnancy style copycat garments, courtesy of Blossom Mother and Child. Despite the fact that Catherine actually wore the dress way before she was pregnant, we feel like we should have known this was coming… What’s next? Think Alexander McQueen will re-release Kate’s wedding dress with a few extra yards of lace?

So for all of you lucky ladies with child, you can now look like the Duchess of Cambridge for a mere £522 (assuming you gauge all of your purchases alongside Kate’s £30,000 sapphire ring). Check out the photos below and tell us what you think of Issa’s latest masterpiece.

Oh, and you can click over to Blossom Mother and Child to buy the sure-to-sell-out dress — if you think you have superior clicking skills, that is.

The maternity version…

And the real thing…
