All About Kate's Adorable Baby Reveal Dress

All eyes were on Kate Middleton Tuesday, when she made her highly anticipated post-baby debut out of St. Mary's Hospital in London.

And the Duchess of Cambridge definitely didn't disappoint, looking gorgeous in a baby blue, polka-dot Jenny Packham dress. Not surprisingly, the adorable empire waist dress generated a ton of interest with women hoping to take a page from Kate's stellar style, but the flawless frock isn't available for sale -- the British designer created the maternity dress exclusively for her baby reveal.

Jenny Packham brand director Blaire McColl dished to Vanity Fair that the dress seen around the world was made using polka-dotted "crepe de chine" in a cornflower blue, but wasn't allowed to give away too many details other than that it's a "full-on original" -- they have no plans to make it available for sale.
