Pretty in Peach for the Wedding of Zara Phillips and Mike Tindall

For the wedding of her eldest granddaughter Zara Phillips to Mike Tindall at Canongate Kirk in Edinburgh on 30 July 2011, the Queen opted for a Stewart Parvin outfit (as did the bride) in peach.
It's comprised of a crepe coat with large self-covered buttons, a silk dress featuring an abstract floral print in peach and turquoise and a straw hat by Rachel Trevor Morgan, trimmed with a two-tone looped bow and feathers. For the occasion, the Queen accessorised with her Courtauld-Thomson Scallop Shell brooch, a favourite of her mother's, and a cream Launer handbag and cream shoes like she had done at the wedding of Prince William to Catherine Middleton a few months earlier:

On 22 May 2012, the Queen chose this outfit for the first garden party of the season at Buckingham Palace, paired with her diamond rose-shaped brooch:

The look was repeated again on 25 July 2012, when the Queen chose it, paired with the Frosted Sunflower brooch, for a visit to the New Forest Agricultural Showground in Hampshire, during her Diamond Jubilee tour of the UK. On this occasion, we saw the dress worn on its own as well:
