First staged in 2002, Shakespeare’s Globe Theatre’s ‘original practice’ staging of Twelfth Night won accolades for its authentic production design. The set, music, dances and costumes were all inspired by the original practices of the Elizabethan stage, with male actors playing the female characters in distinctive ‘white face’ makeup.

Mark Rylance won a Tony Award for his portrayal of Olivia, and in keeping with the original practice style, his costume was a painstaking (and extremely expensive) reproduction of a 16th century Italian noblewoman’s dress. This attention to detail saw Jenny Tiramani take home a Tony Award for costume design.

The Renaissance portraitist Giovanni Battista Moroni also paid close attention to detail in his depiction of the opulent clothes worn by his aristocratic subjects. In a recent event, we took a closer look at Countess Olivia’s outfit to learn more about the effect that wearing such garments would have had upon the 16th-century sitters, and discovered why historically accurate costume is so important for 21st-century stage actors.

Watch edited highlights in the video below, in which Jenny Tiramani and Mark Rylance demonstrate the many layers of Countess Olivia’s clothes, ending with the ultimate finishing touch - the ruff.

Giovanni Battista Moroni is in The Sackler Wing at the RA until 25 January 2015.
