I picked up my first Sheer the other day. I went for Black Laquer, which is a perfect Spring purple. It definitely adds colour and looks beautifully slick when applied. Then it sets to a stain that looks like you've been drinking grape juice... but prettier. Definitely won't be my last. I want virtually every colour, I swear. One thing I noticed, as the colour set- if I was thirsty/ dehydrated, it started to feel tight on my lips, but once I had a glass of water I was find again. It's like my lips shrunk underneath the plump film of the lipstick. I find when it sets, it's just the faintest bit tacky, but feels really nice. It also reapplies easily and evenly, so you don't have to wipe everything off and start from scratch.
My SA also gave me a bunch of samples to try of skin care and of their primer and Luminous Silk foundation. OMG. I'm trying the primer and foundation today and I am FLOORED. I practically fainted when I saw my skin with just the primer on, because it looked like I was already wearing foundation. It completely smoothed out my pores and made my skin look even-toned and silky all over. Then I applied the foundation and I'm in love. Seriously, I'd always worried this formula would be too shiny on me, but it really does look like silk. The colour isn't a perfect match- she only had 3.75, which is a bit too dark- but it's close enough that I can get a good impression of how it would look. I think I'm going to have to go back and get this one in the perfect shade, because this could be my HG foundation.
