For something more on the casually cool side, marry a black crew-neck t-shirt with light blue skinny jeans. If you want to easily ramp up this ensemble with shoes, finish off with a pair of tobacco suede chelsea boots. This ensemble shows that hitting 30 is no reason to shed casual style altogether.
Such essentials as a black crew-neck t-shirt and light blue skinny jeans are the perfect way to infuse played down dapperness into your day-to-day off-duty fashion mix. Dial down the casualness of this look by wearing a pair of white low top sneakers. So if you're looking for fashion inspiration for dressing as you get into your 30s, this pairing is an amazing example.
