For me, I look for dramatic length first, with volume a close second. Seems reasonable and doable, right? You'd think, especially considering there are so many tubes flooding the market. But I've sampled dozens upon dozens of mascaras over the years, from drugstore to luxury, but have yet to find The One. I end up using a tube for a month or two, but rarely replace it. What can I say? My lashes have commitment issues.
