They have like 192850298421904829 colors :D I could never pick a favorite.

I agree with amber_sunshine there's so many! What I love about it is I don't have to do two coats like a lot of nail polishes

i actually prefer china glaze and sally hansen, but i have to say O.P.I.'s "sea? i told you!" is suuper pretty. i love their collection a sephora, too

I like atomic orange but then I like lots of oranges, yellows, and purples. When it comes to color I think we are sissies and need to be more like Indians because they have some many bright colors. Atomic Orange would look good with a cobalt blue stripe in it or something.

i love this brand. so many colors, i don't think i can pick a fav either!

That orange shade is super!

I dont know what my fave color is [depends on the day] but OPI is my favorite company by far!!! I love them. they make the best nail polish!

I love OPI too. I recently bought some from the South Beach collection. It has a smooth coat and there is really no need for a top coat because it's so shiny! I love it!

love the colors♥

ive never used OPI before ive heard of it but ill deff check it out

one of my favorite brands!! ♥

OPI is great brand. I love the color.

OPI always seems to last so much longer that other brands
my favorite color by them is this really pretty blue, kinda sky blue, but not quite as purple. I wear it almost all the time :)

I love OPI too!
