I was wearing my TARDIS outfit at the Doctor Who festival, so I needed to make sure my nails matched... Four coats of nail varnish later... (and it lasted for about a day and a half before I chipped it!)
Jeff would call that Giant's Blue (after his favorite American football team)! If I put that on my nails, it'd be a safe bet that I'd chip it before day's end. I'm pretty rough on my hands!
