When attending a ball, the dress code is white tie. This dress code includes tailcoat, ball gown, regional folk costume and mess dress uniform.
The most important is for the dress to be of appropriate length. It should cover the ankles. All dress models are allowed, but some details are not. It is for example not appropriate for a ball gown to have a too deep neckline. The same goes for a slit which goes too far up the leg or a too short underskirt with transparent outer layers.
Suitable accessories to the ball gown are a shawl or gloves, where the length of the gloves is decided by the length of the ball gown's sleeve length. The gloves should be removed during the dinner but you are welcome to keep them on during conversations and dance. Jewellery is voluntary, but rings are to be avoided on top of the gloves.
The shoes can be with or without heel, but due to the dancing that will take place during the evening is open toe discouraged.
If you prefer to wear a tail coat, this should be black worn over a white wing collared shirt, white waistcoat, a white bow tie, mid or high-waisted black trousers and white suspenders. A white pocket square should be placed in the jacket's pocket.
The sleeves of the shirt should be held together by cufflings. Black, polished shoes with black socks should be worn.
White gloves are optional, and should be removed while eating. Wrist watches should not be worn, but a pocket watch is encouraged! A top hat can also be used, but should never be worn while seated.
Regional folk costume
A regional folk costume should be worn with any accessories which are included in the costume. If this would include a hat it should be worn, but should be removed while seated. The same goes for gloves.
Mess dress uniform
Mess dress uniform from the marine, air force or army can be worn during the ball. As the dress code is white tie, full mess dress is to be worn. Hat can be worn but should be removed while seated, along with gloves.
