A ball gown is the most formal female attire for social occasions (such as White Tie). It is traditionally a full-skirted gown reaching the floor, made of luxurious fabric, delicately and exotically trimmed. Most versions are cut off the shoulder with decollete necklines. Such gowns are typically worn with a stole (a formal shawl in expensive fabric), cape or cloak in lieu of a coat, “good” (couture or vintage) jewellery and opera-length gloves. Standard accessories are dancing shoes and a clutch style evening bag. Where “state decorations” are to be worn, they are on a bow pinned to the chest, and married women wear a tiara if they have one. The ball gown shape has changed little since the mid-19th century. Although artificial fabrics are now sometimes used, the most common fabrics are satin, silk, taffeta and velvet with trimmings of lace, pearls, sequins, embroidery, ruffles and ruching.
