O’Neill, the Irish born creative director at fashion line THEIA, says he was thrilled to outfit the royal, and even became privy to Markle’s pregnancy before the public did in the process.

"The Duchess of Sussex has long been a source of inspiration,” said O’Neill, a native of Co Kerry in Ireland.

“Her classic, effortless and chic style coupled with all the excitement leading up to her wedding earlier this year inspired my Spring 2019 bridal collection which I showed in April."

O’Neill continued, "When her stylist reached out to inquire if I could make a dress for her Australian press tour, I stopped everything we were doing (my bridal show was just a week away) and immediately went to work on Her Royal Highness’s gown.”

“We completed the gown in 2 days, shipped it out and received confirmation that The Duchess LOVED it, but with one caveat. We needed to remake it with extra seam allowance.”

“We knew immediately why this extra allowance was required, but Mum’s the word, and with less than one week to my bridal show, all hands were on deck once more, we re-made the gown and I literally had to run down Broadway [in New York City] that Friday night to catch the UPS truck making it with just 2 minutes to spare!"

O’Neill’s hard work paid off, as the gown was indeed stunning on the pregnant Meghan Markle. The ivory crepe column gown features flanged shoulders, a jewel neck, and side slit. The shoulders are accentuated with hand embroidered appliques of crystals and micro glass beads.
