These are the lipsticks I wear at the moment, all residing somewhere and everywhere between my desk and my bag!
 L-R: L'oreal Rouge Caresse in Tempting Lilac, Vivo Barely There, Sleek Liqueur, Sleek Naked

 Slight theme going on with these!  They are all fairly muted, lovely, easy-to-wear shades.  Tempting Lilac has a lilac undertone, and is extremely wearable: I tend to wear it over Snob lip liner by Rimmel to give it extra depth.
Barely there is a natural light nude with undertones of pink.
Liqueur is a darker natural nude with some pink in it.
Naked is a very kind of tan nude.  
All are very easy to wear, with moisturising textures because of my current dry lips, and I believe all except Naked would be fabulous on all skintones - Naked would make some skintones look 'dirty' so have a swatch of it.  I am hugely impressed by the textures and colours of the Sleek Lipsticks!
I do find the addition of the Rimmel Lip Liner in Snob underneath gives all of the shades a little extra something!
