Now the main colour I have used is my absolute favourite of all time, cobalt blue. Anything in this colour I adore. This particular polish I am using instantly makes me feel glamorous every time I wear it, and this colour is Sportsgirl's Nail It! in Cobalt (yeah, original name). It is a gorgeous, deep cobalt duochrome, that although is beautiful, is quite sheer and requires at least 3 coats. I think this is great, affordable dupe for OPI DS Magic (an absolutely amazing colour).
If you've been in the beauty community for a while, you would recognize this polish. I first saw it mentioned on FleurDeForce and instantly fell in love! It is varying sizes of chunky and micro deep purple in a sheer black base. You can build it up to full coverage, but I personally just do a coat of a black polish with a coat of this over the top. This is just a fabulous polish that glams up any look!
I really adore both of these polishes, and they always glam up any outfit I'm wearing!
What's your favourite fabulous nail combination?
