A white corset mini dress with 3D floral appliqué, a square neckline and a boned, fitted bodice — the Posy works for the hen do and the bridal shower alike. The appliqué gives the photographs texture; the corset structure does the posture work for you.
Style with satin heels and pearl studs for evening, or white trainers when the celebration is a long lunch. One of those dresses that makes the group photo look styled.
