The bold lip. Honestly? It scares me a little, especially if it is in a shade other than coral or pink (this is only on me of course, I love it on others).
Rimmel has come up with a definite bold lip product, but it's not a lipstick, it's a combination of a lip gloss and a lipstick. Apocalips have a runny texture like a lip gloss but they stay on like a lipstick. This product is super long wear, it is simple to apply with the applicator and they give a gorgeous glossy finish.
I currently own two of the Apocalips:
Stellar which is a pink/coral/red gloss and it is really really bright and vibrant - the definition of a bold lip I say.
Celestial which is almost a mauve colour - it is wonderful for subdued looks, maybe during the winter with a grey jumper on (just an idea obviously). It is bold and yet subtle at the same time, perfect if you are a little taken aback by how strong these apply first go.
The great thing about these (apart from the staying power and the glossy-ness) is that they can be a way to ease yourself into a bold lip, rather than going straight for a matte red lipstick. If these have taken your fancy, you can find them here.
