Although spandex survived the '80s with its reputation a little worse for wear, its near-identical cousin, Lycra, emerged from the decade unscathed--so much so that today, from making sure our skinny jeans always fit to giving that lacy cami some much-needed support, the synthetic fiber is universally hailed as every girl's best friend. And what's good for couture must be good for cosmetics, right? Such is the rationale for Rimmel's Lycra Lash Extender Mascara ($6.69; rimmel.com), a new formula that draws upon the properties Lycra is best known for (superior flexibility and elasticity) to lengthen and curl lashes to impressive proportions. The brand's twelfth lash offering, Lycra goes on like a dream--a single coat yields serious length and separation, and each additional stroke makes fringe longer, thicker, and more feathery (with this wand and formula, you couldn't create a clump if you tried). What's more, it boasts a unique wax-and-polymer blend that resists moisture and preserves curl for up to 14 hours. For a naturally long look, sweep on one coat and go; for uber-flirty, sky-high spikes, curl lashes first, then apply the mascara. Either way, you'll find that Lycra really does make everything fit better. Even lashes. --Zoe Stagg
