I know you've seen at least one person wearing pants/jeans that has rips on the knee section. Jeans/Pants ripped on the knee is one of the most popular fashion trends today. You see celebrities doing it, and normal people you see in different places. The fashion style today considers a lot of hipster type clothing. Combining tight and loose. This style is not only for men, but also for ladies. Most ladies often do it with blue jeans while men often do it with black or dark jeans/pants.
Wearing the pants is one thing but matching it is simpler than you thought. A lot of people wear it with a loose T-Shirt. The shirt often worn with it has a very deep crew neck. It adds more of the the hipster look. Shoes are very important in this situation -- I prefer wearing Oxfords, Wing Tips, and Chelsea Boots. The fancy shoes adds a fashionable pop to the casual fit. The rips only work on pants like blue jeans or dark pants. Colored pants wouldn't look very good in this type. Get Inspired.
