It all depends on the girl, and the tan, and the suit used to get the lines. Endless variations, and some work better than others. For tan lines to be sexy, they have to be fairly sharp lines, and there should be a marked contrast between the two skin tones.
It's all sexy, I mean, come on... It's a naked girl.
Ya hd, golf and farmer tans are very similar. I think I like the look of a man that has been kissed by the outdoors.
However, there is a certain allure to a man that is prim and proper and well kept with no tan at all. It usually means under that crisp and well lived skin, there's an animal that comes alive BCD.
