I always recommend that people live in their new house for awhile before making any design decisions. This gives them time to see how they actually use the different spaces, what rooms get sunlight when, and where they gather when they entertain.
When the owners of this home moved in about a year ago, the “formal” living room was not given much attention. They decided that this room would be a sitting room, but definitely not too formal. The furniture we chose is comfortable, and the light colored fabric lends itself well to the casual feel of the space and keeps it airy. We chose a light, gauzy fabric for the windows, which comes “pre-wrinkled” to continue with the theme.
