Fabulash Mascara Waterproof ($6.49) has the same type of brush as Revlon's original (and amazingly good) Fabulash Mascara, but that's where the similarities start and stop. The waterproof version does hold up when lashes get wet, but the application and wear is far from fabulous. Although this mascara lengthens and provides decent thickness, it clumps along the way, applies unevenly, and flakes throughout the day, not to mention it makes your lashes feel dry and crispy. Almay (owned by Revlon) produces much more reliable waterproof mascaras, as do frontrunners L'Oreal and Maybelline New York.
