I don't own Mac Show Orchid lipstick - from the Amplified range I think - but from my swatch memory and blog snooping I think this little number from Sleek would make a pretty decent dupe. Meet Fuschia 833:
The formula of the Sleek lipstick is very creamy and moisturising, and the colour payoff is amazing. That swatch is just a light swipe.
Am impressed with the Gosh pencils too - very glossy, glide on beautifully and lovely colours, although the range isn't huge. Also picked up Gosh Darling which I LOVE.
It has certainly made the flat hunting a little bit sweeter today...
