As you can see, looking casually refined doesn't take that much work. Just go for a brown overcoat and grey chinos and you'll look amazing. For times when this ensemble is just too much, play it down by finishing with a pair of aquamarine athletic shoes. This getup is super practical and will help you out in winter-to-spring weather. So if you're hunting for outfit inspo for dressing as you step into your 30s, this outfit is definitely worth saving for later.
