Black Leiden gown
The inaugural lecture protocol specifies a black Leiden gown with black lining and a black cap with a black interior.
Togamaker.com examined Leiden’s official inaugural lecture protocol and the university’s explanation of expanded gown entitlement. The sources describe colour, academic cap, clothing underneath, loan gowns, name marking, numbered storage and who may wear a gown at a doctoral defence.
In Leiden, the public protocol makes an inaugural lecture compulsory for every new full professor; it is intended to take place within one year of appointment, in a Leiden gown and cap. Nevertheless, the total population does not equal the annual number of inaugural lectures or new gowns.
Definition: regular and personal-chair full professors with a paid employment contract, counted as people, at the end of 2024, excluding the Health field. Special-chair professors are not included in this population and are reported separately in the source. This sector source is separate from the number of gown sources in the introductory banner.

The inaugural lecture protocol specifies a black Leiden gown with black lining and a black cap with a black interior.
The gown and cap are customarily marked with the owner’s name. A personal gown can be stored permanently under an assigned number in the gown room.
The full professor is responsible for purchase and costs. Anyone who does not yet own a gown can reserve a loan gown for their inaugural lecture.
Since 2024, opponents and co-supervisors may also wear gowns and caps at doctoral defences; the doctoral candidate and paranymphs do not wear gowns there.
The same person may be subject to a different dress rule depending on rank, role and ceremony.
| Role | Publicly confirmed or qualified status |
|---|---|
| New Leiden full professor / inaugural speaker | Delivers the inaugural lecture in a Leiden gown with a Leiden academic cap, even if the person was already a full professor elsewhere. |
| Opponent and co-supervisor | May wear a gown and cap at a Leiden doctoral defence under the expanded protocol. |
| Doctoral candidate and paranymphs | Do not wear a gown according to the official explanation. |
| Full professor from outside Leiden | May join the procession; the Leiden gown remains prescribed for a newly appointed full professor’s inaugural lecture at Leiden. |
A reliable academic gown commission starts with the university, role and ceremony, followed by material, pattern and measurements.
A gown maker should not rely solely on photographs. The protocol recommends requesting current work instructions or information on experienced makers.
The outer fabric, lining, cap and internal construction are individually described as black. Material, sheen and construction must not be guessed from this.
Name marking and an assigned number are part of practical management. Placement and legibility must be agreed before delivery.
A loan gown can cover the ceremony, but it must be reserved in good time and checked for length, shoulders, sleeves and cap.
The public brochure provides many details, but does not replace current technical working instructions or an approved reference design.
The extended right to wear a gown at doctoral defences does not mean that the doctoral candidate or ceremonial assistants wear one.
