Kate Middleton In Armani On Second Day Of Royal Tour In Scotland [PHOTOS]

Catherine Middleton, the Duchess of Cambridge, is a global fashion icon and part of that appeal lies in her willingness to repeat outfits... something a traditionally fashion-conscious celebrity would be to loathe to do. As such, she has had an immense impact on fashion and style statements for people across age groups and is seen as an ambassador for London fashion.

Therefore, when the 31-year-old royal stepped out for the second day of her official trip to Scotland, accompanying Prince William, it was no surprise she looked stunning. Kate Middleton wore the same red Armani coat she wore in 2006, at William's passing-out parade from Sandhurst.

On this occasion, the pregnant Kate Middleton combined the coat with black knee-high boots and gloves and showed off the Strathearn tartan scarf she debuted during the Diamond Jubilee Royal Pageant in 2012.

The royal parents-to-be attended the opening of the Tamar Manoukin Outdoor Centre, held at the Dumfries House in Ayrshire, with Prince Charles. And during the visit, Kate was shocked to see her own look-a-like Barbie doll (wearing her blue Issa engagement dress). The surprised Duchess was then presented the doll by 11-year-old Dayna Miller.

"No! Oh no, is that me? Is that meant to be me? Does my hair really look like that!" she exclaimed.

Later that same day, Kate and William visited the Astute-class Submarine Building at BAE Systems in Barrow-in-Furness.

Twitterverse Speaks

Meanwhile, the Duchess, who is expected to give birth in mid-July, has had a number of comments raised about her pregnancy on social networking website Twitter. Users feel Kate Middleton does not appear to be as far along her pregnancy, judging by the size of her baby bump, as she ought to be at this stage.

She was compared to The Saturdays singer Rochelle Humes and reality star Kim Kardashian, both of whom have much fuller figures at six months.

"@AoifeBeIIe Kate and Rochelle are the same weight. Rochelle at 6 months had a big baby bump. Kate has no baby bump. Hmm."

"@Clicksaycheese Kate Middleton is TOO THIN. I know I keep saying it...but it's true. Her baby is going to be the size of a walnut."

"@casstrotter Princess Kate's five months pregnant and is still skinnier than me."

"@GraceRochelle Kim and Kate are pregnant at pretty much the same time...compare how classy Kate looks compared to Kim... says everything tbf."

"@mowwyheef Princess Kate needs to get some chips down her cause she don't even look pregnant and I swear she's meant to drop in 2 or 3 months."
