To be honest I don't have an expansive nail polish collection and most of the ones I own are drugstore polishes. Recently picked up another shade from my favorite drugstore nail polish line with my extrabucks from CVS (join their beauty program and get $5 in extrabucks for every $50 you spend on beauty related items). The polish retails for about $3 and I picked this up along with a Revlon highlighting powder which was 75% off. I snagged both items for about $2 :)
Sally Hansen's Mint Sorbet is a perfect drugstore option for those seeking a mint green varnish. It has a cream finish but I topped it off with a clear polish with green shimmers. The XtremeWear polishes last super long and I can get away with wearing them for abut a week without major chipping. The above picture was actually taken four days after applying the polish!
What's your favorite summer nail polish? :D
