refresh my memory....Is slightly off a medium or light pink?
For some reason I want to say MAC cremestick l/l in Pink treat is similar to Slightly off but it's been awhile since I've seen slightly off....so...I could be slightly off.
I know this thread is old but am just bumping it in case anyone else was looking for a lipliner similar to slightly off - Malta by Nars is a good lookalike and it's perfect with Syrup and Up the Amp lipsticks
