3. BLACK TIE OPTIONAL

　　3、可选择的黑领结

　　Black tie optional is a contemporary dress code. For men, black tie optional means it's not wrong to wear a tux, if you like—but if you'd be happier in a dark suit and tie, you won't be underdressed. Ditto for women, who can wear just about anything they'd sport to a black tie affair, within reason. An embellished cocktail dress is fine.

　　可选择的黑领结是当代的一种礼服准则。对男士来说，可选择的黑领结意味着，如果你喜欢的话，穿无尾晚礼服不会有错，但是，如果你更愿意选择深色西服和领带，这样也不会太随便。同样地，女士可以穿适合黑领结的几乎所有服饰，而这合情合理。一件缀以装饰的酒会礼服就很好。
