It is desirable that lady guests dress as the promovendi, i.e. in a full-length black gown. Gloves are not worn.
It is also possible to wear a black or discreetly coloured dress, but short sleeves nor short hems are suitable for the occasion. Shoes and stockings should be black or otherwise very discreet. No bags are allowed inside the Great Hall or the Cathedral, but they have to be left at the cloakroom.
