5 Things You Might Don't Know The Purpose Of The Design 

In our real life sometime you might found that you cannot understand what is the purpose of that particular design on some items. Today I going to share with you guys 5 little design you may seen before but still don't know the use of it and it could brings convenience coming into your life when you knew it. 

1.The Loop on the behind of your shirt 

Usually we will saw that the loop on the back of our shirt and most of us think that it is the way that shirt should be design in. But in fact, the loop got a function which let you not required any more hanger to hang your shirt, you can just straight away put it on the fitting room.

That is a romantic tales on the U.S.A on few years back ago, that the boys whom has in relationship need to cut off the loop on his shirt to let other girls acknowledge that his had dated with someone.

2. The small pocket on your Jeans 

Some of us still think that the tiny small pocket on the jeans is to let the design of the pocket become more hierarchy. In fact the first jeans of the LEVI'S has the small pocket on it already, due to the pocket watch was popular on that era. The small pocket on jeans is basically to let them put their pocket watch inside it, but as the times changes now getting less of us buy the pocket watch. The design of this also becoming useless.

3. The extract button and cloth on your shirt 

You will notice that a lot of our shirt consist of some extract button and cloth on it. In automatically we will assume that when original button on the shirt drop out we can use it as a replacement. But in reality, the use of that extract button and cloth is to let us test on washing machine to check that whether it able washes by the machine or not. If that is not sign of distorted and fade, then only we wash the shirt by washing machine.

4.The small holes on the Earphones

Example the Earphones of Apple, these earphones use the holes on it to let air flow in and out of the speaker. In order to release the inner pressure and makes the speaker move more freely and allowing the headphones bring a better quality sound and extract bass for the vocal. This also indicate that if you use the headphones to talk with someone, your voice will be more nature and less noises.
