I don't think you can ever really go wrong with a classic colour combination like blue and white. In all the possible blue shades, white is a happy companion.  I love this bright blue for the summer, it's fun and lively, and always reminds me of a relaxed Stella McCartney vibe.  This Couronne bag is the perfect companion all year round, and it fits Thumbelina perfectly!  I love the colour, its not properly blue or grey so it works with black and blue outfits.
