The bride also wore an embroidered tulle veil, which formed the train, and was held in place with silver leaves and bow, the end of the veil having beautifully worked true lovers' knots in silver. She carried a shower bouquet of double pink carnations, lilies and roses, with silver streamers. The bride was accompanied by Miss Irene Powley, also in pastel bine georgette, with small gold cyclamen, and deeper shades of flowers worked on the frock.
