Consumer Reports tested seven nail polishes, including several that claim to last a long time. All were applied with a base and top coat if the brand had one. Ten panelists tried the disguised polishes at home, while ten panelists received a series of professional manicures, with different polishes on alternating nails. Those were checked at seven, ten, and 14 days.

This Chanel polish is the most expensive tested - 27 dollars for the color - plus another 52 dollars for the base and top coat. But it chipped so quickly, most of the home panelists removed it early. Jessica Vecchiano, "It chipped the next day, even with a top coat and a base coat."

Which are the hands-down favorites? Surprisingly, a two-dollar polish available at Walgreens - Sinful Colors - came out on top. And the base and top coats together are just eight dollars. The polish still looked good after seven days, but it took slightly longer to dry than others.

Another winning polish - ten-dollar C-N-D Vinylux Weekly Polish lived up to its name, still looking good after a week. It doesn't need a base coat, and the top coat is ten dollars.

Also a favorite - this six-dollar Revlon polish promises to last 11 days, and still looked OK when checked on day ten. Jennifer Frost, "It went on really smooth, and they looked really nice, and I felt like I had a real manicure." Base and top coat -13 dollars. So to keep your nails looking their best, pick a polish that lasts. If you want a quick manicure and don't have time for the whole
base-coat, top-coat routine, Consumer Reports found some one-step polishes that looked pretty good at the end of a week. They're Sally Hansen complete Salon Manicure for seven dollars and CoverGirl Outlast for five dollars.
