Pretty in pastel! Kate is a vision in baby blue as she embarks on her second solo overseas visit in Luxembourg as the royals' Brexit charm offensive continues.

The sun was shining in Luxembourg and the Duchess of Cambridge added an extra touch of Spring feeling this afternoon, in a pastel blue coat by Emilia Wickstead. 

Kate, 35, paired the full skirted number with her trusty nude heels and carried a textured nude clutch. 

She kicked off her visit with a visit to the Musze d'Art Moderne, accompanied by Crown Princess Stephanie, who looked striking in a red wrap dress with a ruffle detail at the front.

The Duchess of Cambridge is in the small nation to attend commemorations marking the 150th anniversary of a treaty that confirmed the country's independence and neutrality.

Kate will spend one day in the capital city of the Grand Duchy, touring an exhibition of British artists and visiting a cycling-themed festival, but the main focus will be events celebrating the 1867 Treaty of London.

The visit is likely to be interpreted as another trip being made by a member of the Royal Family in their role as 'Brexit Ambassadors', as they have been dubbed by the press.

Kate visited Paris in March with William in what was seen as the first in a series of European tours by the monarchy to strengthen ties with the continent.

In July the Cambridges will visit Poland and one of the leading EU nations, Germany.

Kate will join Luxembourg's prime minister Xavier Bettel at the Drai Eechelen Museum for an event commemorating the 150th anniversary of the Treaty of London.

The Duchess will be given a guided tour of Luxembourg 1867 - Open City, a new exhibition which explains how the dismantling of Luxembourg's fortifications laid the foundation for the transformation of the state into an open and outward-looking city and country.

At Luxembourg City Museum Kate will attend the launch of a new collection telling the country's history to mark the 150th anniversary, and she will be led on a short walk outside the museum to take in the stunning views of the capital.

Luxembourg is only a small country but over the decades has become a thriving financial centre after suffering the depression of its iron and steel industries.

The country's strategic place between France, Belgium and Germany, and proximity to the Netherlands, has meant it has been at the heart of territorial ambitions of a number of states for centuries.
