We're all looking for practicality when it comes to fashion, and this casual pairing of a light violet crew-neck t-shirt and jeans is a practical example of that. You could perhaps get a bit experimental with footwear and add a pair of dark brown leather brogues to this look. With the departure of snow comes a sense of spring renewal and the need for a summery outfit just like this one. So if you're looking for outfit inspiration for dressing as you reach your 30s, this pairing is a wonderful example.
