I love this little mermaid bag. Especially when it's cold as it always makes any (boring) winter outfit more interesting. As do those shoes. You might argue that the shoes in combination with the bag are too much but I think the navy outfit is modest enough to let those items shine without it looking like a costume. No doubt though that I would have worn the exact outfit when I was 3 years old. My taste did not change much since then. The shoes are proof.
