A blue blazer and jeans are the perfect base for a casually stylish ensemble. And if you wish to easily spruce up this outfit with a pair of shoes, why not throw a pair of dark brown oxford shoes in the mix? As the weather begins to warm up again, it's time to shed those bulky winter clothes and choose a look that's lighter, like this one here. Wondering how you should dress as you move into your 40s? This ensemble is an amazing example.
