if courteasans of braavos are attending feast,shows etc with princes does that suppose to mean noble ladies are absent from social life?Does rich just wear dark colours or really roughspun clothes?

If it’s anything like the historical traditions of Renaissance Italy that gave birth to the courtesan – it’s not that noble ladies are absent from social life, but rather than they’re absent from public venues. They of course did a huge amount of socializing in their own homes and the homes of other people of their class and other respectable venues. 

In Mercy, we’re talking about a theater, and a lowly theater at that. The theater was generally associated with vice – prostitutes did a lot of business at the theater in this period, so for a high class women to be seen at the theater was to lose one’s reputation and good name. Indeed, one of the reasons the Elizabethan theater banned women from acting on stage was that it was believed that actors turned tricks on the side to supplement their wages, on the grounds that if you’re making your money from displaying your body in one way, you must be up for doing it in another.
