How it unfolded.
The five-minute version
What actually happened.
The sack-back gown or robe à la française was a women's fashion of 18th century Europe. At the beginning of the century, the sack-back gown was a very informal style of dress. At its most informal, it was unfitted both front and back and called a sacque, contouche, or robe battante. By the 1770s the sack-back gown was second only to court dress in its formality. This style of gown had fabric at the back arranged in box pleats which fell loose from the shoulder to the floor with a slight train. In front, the gown was open, showing off a decorative stomacher and petticoat. It would have been worn with a wide square hoop or panniers under the petticoat. Scalloped ruffles often trimmed elbow-length sleeves, which were worn with separate frills called engageantes.

The world it landed in
What was on the radio, the screen, and everyone's mind.
Same week, elsewhere
1071 marked the height of the High Middle Ages in Europe. The Norman conquest of Bari represented the culmination of decades of expansion by Robert Guiscard, whose military ambitions reshaped Mediterranean power structures. Simultaneously, the Great Schism between Eastern and Western Christianity (1054) had recently fractured Christendom, making Byzantine losses in Italy particularly significant to contemporary observers. This was an era of feudal consolidation, crusading ideology in ascendance, and the slow decline of Byzantine imperial authority that would accelerate toward 1453.
