Summer Lovin’, had me a Blast! OPI has launched their Summer 2018 collection inspired by the Iconic 70s movie Grease, which is celebrating its 40th Anniversary! With all the colorful characters, songs and styles in this movie, there is plenty inspiration to create some awesome nail polish shades. There are twelve shades available in the collection, plus three shades with a leather like finish. I’m going to review and swatch all the shades of the OPI Grease Collection in today’s post.
