As you can see, Dark Side is an amplified finish which means it's second only to the mattes in pigmentation and wear. For something with slip, it 'sets' and stays put quite well, offering around 3 hours of no-bullshit wear without a base. Smudges out nicely and is a bit twinsy with Diva, sharing its rich plummy depth of colour. Usefully buildable, butching up quickly from a thin wash to almost full opacity in three passes. Dark Side's most valuable trait is this versatility; dark lippys are often patchy when sheered, leaving gungey opaque pigments stuck to your flakes and creases etc, but this shade dabs on smoothly in that respect and obliges you with a nice stained raspberry look. Some have complained that it's a 'dated' 90's sort of berry, but I was there and we didn't really have this shit back then. I personally think DS is a timeless staple. Tomatoes/tomatoes.
