An all-white room gives you the greatest decorating flexibility now and down the line. You can make a room pink without painting the walls – just add colour through furniture, accents and unusual finds. Then, when she’s into purple next year, a few quick updates will be all you need. Scour vintage shops and flea markets for one-of-a-kind pieces that add character and a bit of bohemian whimsy. Refurbishing your own castaways with a fresh coat of paint is another affordable option. A girly, but not too frilly, retreat can’t help but fuel her imagination.
