I do believe that shoes have their own persona. That's why there's a different pair of shoes for a different ensemble outfit. Sometimes the shoes speak for itself, noh.
Like for example , Sneakers, if you'll see them , you're going to think of wearing it with shorts, or skirt ,that's the length is decent enough to wear, or with jeans. As if , it tells you what to pair it with.
Another example , for this oxford cut out shoes. Aside from the fact that this pair makes me think of Paris, if you're going to wear this, you really have to prep-up or else , the whole outfit will fail. I tell you, ive seen people wear this in a wrong way.
In the end, it's still up to us how to interpret those shoe messages :D
