Kate Middleton appears a little red-faced while looking at a racy dress with naked lovers on it

The mother-of-three had a sweet and almost childish reaction to some suggestive dresses depicting the human form, created by Scottish designer Christopher Kane, and it was all caught on camera.

On their first royal engagement of the year, Prince William and Kate Middleton traveled to Dundee, Scotland. Among other things, they toured the recently opened V&A design museum, where the Duchess experienced an awkward moment.

As the Countess of Strathearn, as she is known in Scotland, was given a guided visit at the V&A, Middleton had a hard time holding her laughter and was visibly blushing when she ran into Kane’s design featuring naked lovers.

Senior Curator Joanna Norman was photographed alongside the royal couple as they contemplate the impacting dress that is part of the designer’s Autumn/Winter 2015 collection.

While Kane is known for his irreverent style favored by celebrities, Middleton is much more conservative in her choice of dresses. On her visit to Dundee, she paid tribute to her hosts wearing an Alexander McQueen tartan coat dress.

As patron of the institution, Middleton gave a short speech during her visit, on which she talked about the benefits the new museum had brought to Dundee’s waterfront area.

“Last February, I was delighted to become Patron of The V&Ain London. Now, nearly a year later, I’m thrilled to be standing in a brand new V&A: one which has been built for the city of Dundee and for Scotland, and which is already picking up international awards,” she celebrated.

“In its first four months alone, it welcomed over 360,000 visitors – a truly remarkable feat,” said the Duchess.

Middleton took some time to take a walk outside to greet the crowd that had gathered to see her, and she even had a short chat with a well-wisher, to whom she told that 9-month-old Prince Louis is a “fast crawler.”

She was also captured as she let a young girl stroke her hair, and you can tell that she was having a good time because of the big smile she flashed.

The official royal visit also included meeting with Michelin factory workers to address the challenges that will face finding new jobs, as the factory is about to close.

“For everyone affected, the hope is that all of you sat in this room can find a positive way forward. You all deserve enormous credit for sitting around this table together to find a constructive way forward,” William told the workers.

The Duke and Duchess of Cambridge might be called Earl and Countess of Strathearn in Scotland, but in private they have their own names for each other, and they have been revealed recently.

According to the Sun, Middleton calls her husband “baldy,” while Harry calls her “Duchess of Dolittle.”
