refinement (n)-fineness or elegance of feeling, taste, manners, language, etc.
For me, refinement is synonymous with class. So what does refinement mean when it comes to your wardrobe and style? Classicism. Here's what refinement in style means to me:
A subtle, yet sophisticated watch tucked under your sleeve. It does not scream for attention, but it is quite noticeable.
A whimsical touch to a traditional outfit. Colored socks add the perfect, unexpected touch.
A simple, understated pair of sunglasses to match the style of the outfit. Tucked away, and always at the ready.
A scarf to add the finishing touches. Whether its a light-weight spring scarf, or a chunky one for winter, scarves tie everything together.
