Don't forget you have to live there!
Style shouldn't become so important that you can't relax in a room. Successful decorating should be livable, even if the look is formal. This high-end, traditional living room features pretty accessories, art and architectural details yet it still invites quiet reading or entertaining guests.
Invite friends over. Your space should encourage conversation, laughter and entice your guests to want to stay. What use is an super-stylish sofa or armchair if it's also uber uncomfortable.
