This pairing of a multi colored vertical striped blazer and black chinos is a lifesaver when you need to look casually smart in a flash. To introduce a bit of zing to your ensemble, complete your ensemble with black suede loafers. So as you can see, this getup is a really smart idea, especially for awkward transition weather, when the temperatures are dropping. As you're transitioning from your 20s to your 30s, you want to start dressing in a more refined manner. If that's the case, getups like this are a life saver.
