This was before the last mani photos and prior my getting them filled, so they don't look quite as amazing, but the polish does.
It's Sephora Formula X in Hocus Pocus. I found it at Marshalls in the clearance for 3 dollars. In the bottle I wasn't 100% sold but on the nail, I utterly love it.
It's just a super pretty polish and I found it at a great deal, if you see it you should totally get it.
