The best
Pros: almost invisible, easy to use, cheap<br /><br />Cons: shipping may take a while<br /><br />I've used several tapes and this is the best.  I've found single-sided tape to be the most inconspicuous and transparent, whether I have makeup on or not (double-sided tape is the most conspicuous).  It's easy to peel off the paper, I can reposition if necessary (though not recommended), and it stays on all day.
