if you can afford it, why not?
some brands like prata (i always call it that) and JPG aren't worth
the money...
but some brands, like Aigner and Coach.. you pay for the quality
rather than the logo.. if you notice, there is no Aigner or Coach
knockoffs.. that's because they cannot make knockoffs as good as
these without becoming almost as expensive...
so, do think about that when you buy branded stuff
