One too many accessories.
When it's cold as hell outside, it makes sense to wear a scarf, gloves, and a beanie. But as the weather gets warmer, less is much, much more. There's no reason to be wearing a pocket square (in a denim jacket no less), a lightweight scarf, multiple bracelets, and a belt. Pick and choose two and go with it. You don't want to be the dude carrying his scarf around when it gets too hot.
