In my new house in the little girl's room, I'm doing pretty Cabbages and Roses pink and green linen roman blind, pink walls (Dimity by F&B) white painted sleigh bed, white bedside table, white Ikea bookshelf, bit of bunting, chandelier, shelves on the wall for pretty things and Ladybird books, peg rail for dressing gown etc, white painted wardrobe, white painted floorboards, pink and white rug, vintage green painted chest of drawers. Baskets under the bed for storage, toy chest, dolls house. No theme, except in colour.
we painted 2 walls BRIGHT pink,and papered the window wall and one other with disney princess paper (very pale pink) and she has a white fluffy carpet, the 2 painted walls we have the disney princess wall stickers, and her curtains are the same bright pink as the opposite walls,
i love her room, we decided on the white carpet as it will grow with her,better than a pink one!
How about simple colours on walls and floors and really bright accessories in bright colours, eg hot pink/apple green/turquoise? Colourful rug, bedlinen, prints etc look great against white walls and exposed floorboards. I like Miffy prints/pics for little girls rooms, sweet but not too pink and girly.
