Cargo pants are a great choice for a casual day out. They're comfortable and stylish, and they can be dressed up or down depending on the occasion. When choosing a shirt to wear with straight-leg pants, it's important to consider both the color and the style of the shirt. For a more casual look, pair elastic waistband cargo pants with a denim shirt or a simple tee. If you're looking to dress up your cargo shorts, opt for a button-down shirt in a solid color. For a unique twist, try pairing cargo trousers with a printed blouse or a cardigan. No matter what shirt you choose, make sure it fits well and is comfortable to wear. With the right shirt, you'll be ready to take on anything the day has in store.
