Hi as a fellow pale snkined female and as someone who has ALOT of past experience with tanning I would be happy to answer your questions. It really all depends on you.If you don't plan on continuing to tan and you just want to tan this one time and expect any type of tan outcome, get your spray tan.If you are going to continue to tan, then you should lay in the tanning booth. You won't tan by tanning one time in the bed.1. If you are comfortable going naked, then this is your best bet. No tan lines and it is flawless but if you are not comfortable going completley naked, you should go in with a thong and braless. And if THAT is too naked for you then I would suggest a bathing suit. 2. A spray tan will last longer because one tanning session won't tan your skin. You have to continue to go tanning to get brown. But if you go tanning regularly in a tanning bed, that always last's longer than a spray. A spray tan usually only lasts a week, if that. If you consistantly tan, it won't ever fade. Hope this helped! =]
