it's not that it's necessarily important to all who buy these brand names, but rather the "quality" of the things you are buying. Usually branded things are of better quality than no-brands *though not always*, but for the most part, yes.
For those who do not even look at the material and only at name brands, well they are just ignorant people, who follow what others do, so just because they see others want or have something, they decide they want and need to have this too solely for that reason, which is stupid.
And the branded stuff is so expensive for two reasons, once being they "usually" are made with top quality material which will be durable for a longer period of time, AND for the popular name. However, sometimes the material sucks! and you are still paying a high price, so one must be smart and take better notice in what one is buying...
As for your saying about girls want guys to buy them only branded stuff, that's ridiculous! (from my point of view)
Most people prefer to be given something of good durable quality, I would assume, and on a more personal note, I wouldn't want my bf to buy me something just because "I" want it... but rather more because he felt the need to do it out of his own will. That's the sweet part! Even if it was not a branded item.

I want them to feel a bit appreciated and this is one of the many ways you can spoil them.
