““Should the girls decide to go for a walk, they would need to change into a different outfit, a light woollen tweed suit and sturdier boots - but on simpler days, such as for the garden party, they make mercifully few changes. Cora, like many married ladies in her position, takes the opportunity on quiet afternoons to take off her corset and wear a teagown for an hour or two before getting into her evening dress. Its huge advantage was that it was always ornately decorated but simply cut, meaning it was the only garment a woman could conceivably get in and out of alone, as it could be worn without a corset underneath. Worn between five and seven o'clock, it gave rise to the French phrase 'cinq a sept'. This referred to the hours when lovers were received, the only time of day when a maid wouldn't need to be there to help you undress and therefore discover your secret. Lady Colin Campbell's divorce had hinged on the fact that her clothes had clearly been fastened by a man who didn't know what he was doing; when her lady's maid saw her for the next change, the fastenings were higgledy-piggledy. But for Cora, the teagown is not for any illicit behaviour, just for respite from her underpinnings.””
