Pick some light, girly accents to add a feminine touch to the straight lines of the furniture. Miranda kept antique perfume bottles on her dresser, and chose sheer, airy curtains to let light into her big, pre-War apartment. Make sure to pick up a Starburst Mirror for above your mantle that's hard, sharp, and unusual like Miranda. Leave other decorative touches to a minimum, maybe just some vases, a bedside childhood portrait, and candles. Hang abstract black and white photo prints that are intriguing and sexy. Install clean and classical crown moldings. Purchase a Tibetan-inspired, somewhat mystical painting to hang in the dining room, and lay down a muted toned brocade rug.
Let the light in with sheer curtains, so you cast soft shadows into the room. Pick a geometric lamp for your bedside table lamp, and put a tall, textured wooden floor lamp and a crystal sphere table lamp next to the couch. Hang boxy, rectangular white pendants over the dining room table—nothing fussy, it doubles as a workspace, remember?
Whatever you do, think conservative. Choose proportion over embellishment, and neatness over clutter like Carrie's creative crib. Choose products that are lean, simple, understated, and very well-made. This is, after all, the Upper West Side.
