Frankly speaking I think the belt width should be a little bit narrow would be more better. Now the belt width is 3.5CM, I think 3CM is enough. And buckles size is too big, it looks not exquisite.
And the belt mentioned which can use both side, but use one side such as black side no problem, the belt have close curve. When you want to select the brown side the belt have lateral curve...

Others part are all OK, no question for it. So I give 3 starts for it.
