New in: 3 must-have mascaras from Marc Jacobs, Elizabeth Arden and Makeup Forever

I'm quite happy to admit that finding the ultimate mascara is a bit of an obsession of mine. When you're blessed with invisible blonde lashes, finding a decent one becomes less a matter of vanity and more one of total necessity! Over the years I've tried hundreds of different ones with varying results, finding my one true mascara love in Too Faced's Better Than Sex.

Now, just because I'm in a long-term relationship with one particular mascara doesn't mean I stop hunting around for the next big thing. What can I say, I'm fickle! So I wanted to run you through three others that i'm currently loving at the moment.

Elizabeth Arden's Grand Entrance gives great definition  and curl to lashes, with just the right amount of volume and length. I love the fact that you can layer this one up to customise the amount of volume you get - one coat is very natural, two is a bit bolder and three is my favourite for a night out. The curved silicone brush gives great root lift, and also helps to separate the lashes to avoid any clumps. It has a tiny little brush on the end, meaning it's easy to get into those dinky little corner lashes without poking yourself in the eye with the wand and the super black formula doesn't flake or smudge, even after a 12 hour day. £22

It's great to see Makeup Forever in Debenhams, as it makes it soooo much easier to get hold of! The Smoky Extravagant Mascara is a must-try in my books - I love the fluttery lash look it gives. Like the Elizabeth Arden mascara, this one is a buildable formula; I usually go for two coats in the day time for a really fluttery finish. The conical brush does take a little getting used to, but with a bit of practice you can get every single lash with minimal effort. The colour is a slightly softer black shade than your standard black, which is quite flattering, especially if you have naturally lighter lashes like me. £18

Marc Jacobs' beauty line has just launched into Harrods, making it much more accessible than it had been up until now (it was available in-store only at their boutique in Mayfair, but that's about it). The Velvet Noir Major Volume mascara definitely lives up to it's name - it packs on the volume in just a couple of coats and manages to do so without clumping. The brush is about the right size for me, not too big and not too small, giving decent lift at the roots that lasts all day. If you have oilier lids, then you might find that it smudges a little towards the end of the day. I noticed a little bit of transfer after a 14 hour day in a very humid New York, but to be fair, I was definitely putting it through it's paces! £20
