How's this for a mascara recommendation?  In the current installment of People's 50 Most Beautiful, Champion swimmer Amanda Beard says she uses Maybelline Volum' Express Waterproof Mascara when swimming to look good.  Considering she spends most of her time in the water, that's quite a product endorsement for the waterproof promises of Maybelline's classic line!  

I wear makeup in the water. I always wear a waterproof mascara, Maybelline Volume Express. All my makeup is waterproof, even my concealer."

Hmm, now if she can go into a little more detail on that concealer, we'd be set!
