The organiser of the occasion specifies the dress code and whether decorations are to be worn. The invitation should mention ‘white tie (full evening dress) and decorations’ or ‘dark suit and decorations’. Only miniatures can be worn with a dinner jacket used as formal attire, when required in the invitation.

For ladies, decorations are worn as indicated in the dress code for the corresponding gentlemen’s attire. In the case of ladies’ dress that corresponds to a dark suit, miniatures may be worn instead.

At ceremonial and other special occasions held outdoors, full-size decorations may be worn on an overcoat at chest height.
