A tea gown or tea-gown is a woman's at-home dress for informal entertaining of the late 19th to mid-20th centuries characterized by unstructured lines and light fabrics. Early tea gowns were a European development influenced by Asian clothing, part of the japonism of Aesthetic dress. Later tea gowns featured frothy or feminine detail:

Every one knows that a tea-gown is a hybrid between a wrapper and a ball dress. It has always a train and usually long flowing sleeves; is made of rather gorgeous materials and goes on easily, and its chief use is not for wear at the tea-table so much as for dinner alone with one's family. It can, however, very properly be put on for tea, and if one is dining at home, kept on for dinner. Otherwise a lady is apt to take tea in whatever dress she had on for luncheon, and dress after tea for dinner. One does not go out to dine in a tea-gown except in the house of a member of one's family or a most intimate friend. One would wear a tea-gown in one's own house in receiving a guest to whose house one would wear a dinner dress. – Emily Post, Etiquette, 1922.

Tea is an aromatic beverage prepared by pouring boiling hot water over cured leaves of the Camellia sinensis plant. The term also refers to the plant itself. After water, tea is the most widely consumed beverage in the world. It has a cooling, slightly bitter, astringent flavour which many people enjoy.

Consumption of tea (especially green) is beneficial to health and longevity given its significant antioxidant, flavanols, flavonoids, and polyphenols content.

Consumption of green tea is associated with a lower risk of diseases that cause functional disability, such as “stroke, cognitive impairment, and osteoporosis” in the elderly.

Tea contains L-theanine, and its consumption is strongly associated with a calm but alert and focused, relatively productive (alpha wave dominant), mental state in humans. This mental state is also common to meditative practice.

The phrase herbal tea usually refers to infusions of fruit or herbs made without the tea plant, such as rosehip tea or chamomile tea. Alternative phrases for this are tisane or herbal infusion, both bearing an implied contrast with "tea" as it is construed here.
