"You can take it if you like it," Annalise offered Cara since Cara was the one to enjoy dresses.
Cara imagined herself wearing the dress, but she also knew it would be rude to take the dress from Annalise. Annalise should take it and dress up at least once. They were plenty of festivals soon to come where they got to leave work and have fun.
Cara would not have Annalise wearing the dresses she wore when working to those festivals. Just because they were maids did not mean they should not dress up.
