ну в чем вы были ,это не значит ,что так нужно)Debrett’s, the UK’s most definitive source of social protocol, says in its New Guide to Etiquette and Modern Manners that “Women wear long, formal evening dresses.  Short frocks, no matter how glamorous, are not acceptable and trousers should not even be considered.  These rules are particularly strictly adhered to in Scotland.”  If the evening is to include rigorous dancing the book advises against strapless dresses, big jewellery and unrestrained long hair and suggests comfortable shoes.  Evening gloves remain correct although they are rarely used by young women and “are no longer compulsory” according to the Debrett's online etiquette guide.
