Many pPeople of all ages are interested in buying brand name products currently, specifically clothing.

Despite their gigantic price difference with others, not everyone views this as an issue.

They don't have enough money and also think that there is no need to spend aso much money on a single product, just because it is a branded clothing.

This type of customers doesn't see clothing as a sign identity, but they buyonly buy new clothes whenever they need them.

For this reason, they rarely follow any fashion trends.

They are more interested in the price, the quality and the utility of them clothes.

For example, when winter is coming, the first thing that these families think isn't "what is the fashion of the moment?", but what material the clothes are made of, and whether they are suitable for the cold.

Those in favour of buying brand name products, view ithis as a hobby.

It is true that they are more expensive; however, they are normally made of with better quality materials.

"with better quality materials" also works :)

For this reason, they are going to have a longer lifetimewill last longer.

In conclusion, it's a fact that people are buying branded products more than ever, and that it can make life more fun for some people, but iI am not in favour of this.

I strongly believe that people don't buy brand name products for their quality, but they view them as a kind of sign of statustatus symbol.

The advantages and disadvantages of buying brand name products

Many people of all ages are interested in buying brand name products currentlythese days, specifically clothing.

I feel like this is more in line with what you meant.

Despite their gigantic price difference with otherbetween them and other products, not everyone views this as an issue.

"Others" is most often used to refer to people, and "X's difference with Y" sounds somewhat strange. It should be "the difference between X and Y."
Every"one" is singular (just like no one, someone, anyone, etc.).

They don't have enough money and also think that there is no need to spend so much money on a single product, just because it is a branded piece of clothing.

You cannot say "a clothing." You must say "a piece of/an article of clothing" instead. (Same goes for "clothings" vs. "pieces/articles of clothing")

This type of customers don't see clothing as a n expressigon of their identity, butand they buy clothes wheneveras they need them.

"Sign identity"? I wasn't sure what you meant, so I took a bit of a guess.
If you say "but," it sounds to me like you're saying something that contradicts the "don't see clothing as...." In actuality, you're giving additional info along the same vein, so I think and is more suitable here.

For this reason, they rarely follow any fashion trends.

They are more interested in the price, the quality, and the utility of them.

Made of is fine and made with is also fine, but made of with is not.

For this reason, they are going to have a longer lifetime.

I strongly believe that people don't buy brand name products for their quality, but theyinstead view them as a kind of sign of status.

Again, I don't know if it's just me, but if you say "but they" here, it gives me the wrong idea about what "but" is trying to contradict.
I could have used ", and they view" here too like I did above, but this sounds nicer to me here. You could also have used "but instead" in the sentence above for the same effect.
