I don't know how many of you guys have access to Yves Rocher, but right now my favourite daytime/subtle evening mascara is their Sexy Pulp. I'm also having a lot of fun with the crazy Avon Mega-Effects one with the torture-implement brush. It's a bit of a pain to get the hang of it, but once you're used to the brush it can get some really dramatic effects.
I like the brush but not sure how I feel about the formulation. Some days I like it, some days I don't.
