A quick post from the office...
I have basically just swatched these lipsticks onto my arm, taken a quick picture and wiped everything off... of course someone walked in the door while I was scrubbing and scrubbing, can you never have a moment of peace and quiet at work?!?
Anyway, I bought "Watch Me Simmer" from MAC's Shop, Cook Collection after all, I had vowed not to do so because I already had similar shades but I succumbed in the end... bad bad Blusherine!
But I know you want comparison swatches, so here we go:
(click to enlarge)
Hibiscus is a Cremesheen, Surf Baby Collection, swatch
Vegas Volt is an Amplified, permanent, swatch topped with lipgloss
Watch Me Simmer is a an Amplified, Shop, Cook Collection
Impassioned is an Amplified, permanent, swatch topped with lipgloss
Costa Chic is a Frost, permanent, swatch topped with lipgloss
Hope that helps!
