At New York Fashion Week, matte nails were as trendy as ever, but unfortunately, we can't just all run out and buy matte polishes to get in on the style. Luckily, all you need is Essie's Matte About You Matte Finisher ($10). This top coat instantly turns any polish matte, even your glossiest hues. Plus, it's quick drying, which makes messing up your manicure that much more difficult. Stay-for-days polish jobs are doable at home — even for those of us who are less dexterous than the rest.
