Halterneck bikinis, swimming suits, shorts, socks, uneven applied sunblock. These are all very good reasons for the existence of tanlines. But as long as you do not go to a nude beach there is no way around them! Here are some examples from Webshots and Flickr:

But this photo highlights something important - the use of tanlines as a way to measure the progress of your tan.

In the start of your vacation you
may barely see the difference of the bikini area and the rest of your skin, while towards the end you get a serious tanline to keep an eye on.
