We all seek functionality when it comes to fashion, and this off-duty combination of a light blue crew-neck t-shirt and light blue ripped jeans is a vivid example of that. When not sure about what to wear when it comes to footwear, complement this ensemble with white and black athletic shoes. Stick with this one if you're looking for a standout summery ensemble. This combo shows that in your thirties your style options are pretty much limitless.
