Here is a comparison that I did a while ago...Sephora by OPI - Gleek Out (from the Glee Collection) and OPI - Simply Smashing (from the Serena Williams Collection).Close, but not dupes!Can I justify having both?You know I can!Gleek Out leans more green while Simply Smashing has a bit more yellow to it.Reminds me of a sparkly tennis ball!But, then again, I’m sure that’s what Serena was going for.Love them both!
