The cocktail dress. This look is a bit fancier than semi-formal but conversely a little less rigid than black tie optional. The cocktail dress is popular event attire. You will find most cocktail dresses are typically knee-length. If the event is in the evening, why not go for a darker colour conservative dress? If the event is scheduled for the daytime, something lighter and comfortable might be more appropriate. One caveat, try to avoid cocktail dresses in mini and maxi lengths. The most classic cocktail dress is the LBD or little black dress.
Black tie. Black tie is most often worn at an evening event. Women are expected to wear floor length gowns. Black tie is a little less formal than a white tie event. You might even get away with a luxurious cocktail dress! Women should avoid anything overly tight or with gaping slits. To be on the safe side stay away from anything considered tacky!! Stay away from short dresses and again shy away from that bawdy over the top jewelry. Simple is better when it comes to bracelets and necklaces.
White Tie. The most formal invitation you can receive is the one requesting white tie attire. White tie can also be called full evening dress. This is a posh gathering. At this high-caliber event guests are expected to present themselves with grace and dignity. White tie is reserved for very unique or prestigious events. Guests will go the extra mile to look grand. Women should don floor length gowns, jewelry, and heels for an elegant look. Only during a white tie event would you expect to see long gloves added to the finish the ensemble.
