While fashionista Kate wore her dress with metallic Jimmy Choos for her soiree, Alexandra opted for shoes more appropriate for the daytime nuptials – nude patent heels – which are incidentally one of Prince William's wife's trademark looks.
It wasn't just Princess Alexandra that had succumb to the 'Kate effect'. Witnesses at the wedding who included Lola Toscani and Maria Sanchez also wore the floor-length number.
Princess Alexandra wasn't the only member of the Grand Ducal family who had looked to her royal contemporaries for fashion inspiration.
The beautiful bride Princess Claire of Luxembourg wore a dress very similar to the one chosen by Princess Stephanie of Luxembourg for her wedding to Prince Guillaume last October.
