"The gown is in a Spanish style. We have a fitted gown based on the picture of the pattern of a woman's fitted gown taken from Geometria, y traça, by Burguen (as discussed in Janet Arnold's Patterns of Fashion). The sleeve style is also Spanish and is called a Spanish great sleeve." Guy's Costumes (http://www.wyrdrune.com/Costume/)
