Right now I think my favorite drugstore brand nail polish would have to be NYC. So far I've found that the application is nice and the polish last around 5 to 7 days without chipping.
Since I grew up only 15 miles from New York City, I can really relate to their latest collection which is named after places in the City. Like, Radio City Rose, Chinatown. Broadway, Central Park, Bryant Park, East Village, West Village, Times Square, 5th Ave. and Madison Ave, to name a few.
The polish in the picture is Lincoln square Lavender which is a pretty pinkish lavender that seems to go with almost anything I wear. LOVE IT.
