Yellow Polka Dot Bikini is the colour of a tennis ball; a neon yellow with a teensy hint of green, that dries to a satiny finish. I'm not a yellow lover, but this is so cheerful and happy that I couldnt resist it. Yellow Polka Dot Bikini is meant to be a dube for Orly Glowstick and is cheaper to buy, so that is another plus in it's favour.Out of China Glaze's huge neon polish range Yellow Polka Dot Bikini is one of the stand outs to me as you can get it opaque within 3 coats without too many streaks when you skip the white base, which is a problem I keep encountering with their older neon polishes that I've been trying. However this is still a neon that really does benefit from being layered over a white base; whilst the shade is bright within three coats when worn alone, using two coats over a white base will give you the true neon shade that you see in the bottle without any streaks. The polish is smooth and bubble free to apply, and dries extremely quickly; within one minute.I can't really complain about my slight problems with the formula; all neons work best over a white base, dry matte or satin, and are a bit tricky to work with, because of the intense colour pigments the formulas contain.
