Have you ever been to a Hindu wedding?

A wide variety of colours, ranging from a slightly orange yellow to a deep orange red, all simply called saffron, are closely associated with Hinduism and Buddhism, and are commonly worn by monks and holy men across Asia.

In Hinduism, the divinity Krishna is commonly portrayed dressed in yellow or yellow orange. Yellow and saffron are also the colours worn by sadhu, or wandering holy men in India.

In Buddhism orange (or more precisely saffron) was the colour of illumination, the highest state of perfection. The saffron colours of robes to be worn by monks were defined by the Buddha himself and his followers in the 5th century BC. The robe and its colour is a sign of renunciation of the outside world and commitment to the order. The candidate monk, with his master, first appears before the monks of the monastery in his own clothes, with his new robe under his arm. and asks to enter the order. He then takes his vows, puts on the robes, and with his begging bowl, goes out to the world. Thereafter, he spends his mornings begging and his afternoons in contemplation and study, either in a forest, garden, or in the monastery.

According to Buddhist scriptures and commentaries, the robe dye is allowed to be obtained from six kinds of substances: roots and tubers, plants, bark, leaves, flowers and fruits. The robes should also be boiled in water a long time to get the correctly sober colour. Saffron and ochre, usually made with dye from the curcuma longa plant or the heartwood of the jackfruit tree, are the most common colours. The so-called forest monks usually wear ochre robes and city monks saffron, though this is not an official rule.

The colour of robes also varies somewhat among the different "vehicles," or schools of Buddhism, and by country, depending on their doctrines and the dyes available. The monks of the strict Vajrayana, or Tantric Buddhism, practised in Tibet, wear the most colourful robes of saffron and red. The monks of Mahayana Buddhism, practised mainly in Japan, China and Korea, wear lighter yellow or saffron, often with white or black. Monks of Theravada Buddhism, practised in Southeast Asia, usually wear ochre or saffron colour. Monks of the forest tradition in Thailand and other parts of Southeast Asia wear robes of a brownish ochre, dyed from the wood of the jackfruit tree.

Acceptable for women is colours any colour but not entirely white
For men, white is cool - white 'dhoti'(loin-dress) & white 'punjabi/kurta' (longish shirt) were de rigour (equivalent of tuxedo & bow-tie) even a few decades ago, now men wear colours.
Bottom line is it needs to be ornamental, gorgeous, jazzy or even royalist. But not sober, or business suit not 'formal' but festive.
Women will wear their latest jewellery, mostly gold and more.
Just a little bit of cleavage is okay,but not too much LoL
Huge spread in food - over spiced, over eating, wasteful.
Will post a pic of me in traditional dress
