Tamara Says: Waterproof mascara is a must for times when you’re in and out of the pool, lake, or ocean. Diorshow has been my absolute fave for years because it really delivers thick, full lashes, and the waterproof version travels with me all summer. I’m going to do it in blue, the offbeat choice and a throwback to the 80’s that looks totally right with swimwear and resortwear, and next to blue skies and blue water.
