I used Wet 'N' Wild Fergie nail polish in Disturbia then apply this polish on top XoXo... & BAM! Amazing beyond words! Gosh have girls asking what polish I'm using.. But I would not use XoXo by itself because type of glitter polish you use on top of a vibrant or deep color.
I'm a sucker for holo, but this is just leaving me lukewarm. It's a silver glitter in a clear base, with holo bar glitter. Even layered over a dark blue... eh. Maybe it's just too busy. Maybe it's just that bar glitter rubs me the wrong way. The formula is a little gloppy but that's probably due to the amount of glitter in it. This was $3.50 at CVS, but I got it during a BOGOF sale.
