Boxershorts
If you talk about boxershorts, you have to distinguish between those that are really boxershorts, and the ones that should not be called boxershorts. Skimpy little short cut underwear can't seriously be considered as boxershorts, since the only reason that they exist is probably to hide the private parts to the public. Yes if you have the body of a model, you might look good in these, but if you are the average Joe, you need a boxershort, that really fits you.
What most men want is a short that they really like. That means that men want a boxershort that has the logo of their favorite sports team on, or something that is cool, like a cannabis leaf or a dollar bill on it. Men look at their boxershort like a poster on their bedroom wall. It is something that they represent, that they live with everyday, or a hobby. The shorts can't just be plain white or black. It has to show something to the world that represents the man who wears it. The fancier the look is, the better it feels.
The shorts also have to be loose on the hips, since men don't want to be bothered by tight pants which give them stripes on their skin, after they take it off. Men don't want silk either; they want cotton all the way. The life of a boxershort will be an average of 3-5 years, which is pretty good, considering, that most other accessories fro men will be thrown away after a year. The shorts also have to be very baggy, so it kind of looks like a basketball short, but still is somewhat of an underwear.
