Last week, Crown Prince Haakon and Crown Princess Mette-Marit of Norway attended a private birthday party at the Norwegian Students' Rowing Club in Oslo. The birthday party was held on the occasion of the 60th birthday of Per Høiby (brother of Crown Princess Mette-Marit). At the birthday party, Crown Princess Mette-Marit wore a ruffle trimmed silk blend maxi dress by The Vampire’s Wife.
