Let's face it - while we need the support of a properly designed sports bra when we're exercising outside, we could do without the awful tan lines. Finally, we can have both, thanks to the Naked Sports Bra
($42). This racerback piece keeps our girls where they should be, but is made from a tan-through micromesh fabric. We'll just need to remember to put our sunblock on underneath it, or we'll have a whole other kind of tan line problem.
