I was asking Butterfly a polish question in another thread and between that and the perfume survey, I was inspired.
What are your favorite nail polishes, brands and colors, and also your best nail care tips? I know we have talked about 'store bought' nails before, but I have the 'home grown' variety, though I suppose for favorite polishes, it doesn't really matter.
One of my best tips: 100% pure acetone. Availiable at Sally's, and even Walmart and other places like that. Makes removal SO easy. I frequently wear a French manicure, and it is much easier to put the white all over the top half of the nail and then create the arch with acetone and a paint brush.
My favorite red (red is the only color I wear) is by Orly, called 'Crawford's Wine'. It's similar to OPI 'I'm not really a waitress' - metalic red (you that Ferarri red color that glows as you...

). I also ADORE 'Firecracker' by Revlon, a gorgeous cherry red with metalic glitter. It needs a couple good top coats though since the glitter goes on a bit rough.
I have trouble keeping polish on around the tips of my nails - my nail beds are really curved, so the corners begin to turn under easily. I've recently purchased a base coat that is supposed to help polish adhere. The verdict is still out on that one. So far, it seems like my tips chip less, but if they do chip, the chip is bigger than without the base coat.
The only other thing I can think of right now is the hydrogen peroxide bath...if nails start to yellow, give a peroxide bath and a little scrub with a nail brush to whiten them up. I've heard bleach works too, but I can't imagine that's too nice on your skin.
Favorite colors/brands? Any other good tips?
