I almost missed it, but june's not over yet, so it's still Pride Month. Here's my rainbow mani.
I've seen a mani like this (much better executed, though) somewhere in the internet and loved it so much, I decided to copy it. I forgot where it originated, so if you think I copied your mani, leave me a comment, so I can link you.
I started with a white base (two coats of Essence Wild White Ways) and added the rainbow two colors per nail with a nail art brush. My colors are (from left to right on my nails): red Born Pretty Store stamping polish, MoYou London Pumpkin, MoYou London Sweet Custard, green Bron Pretty Store stamping polish, blue Born Pretty Store stamping polish and MoYou London Purple Mouse. One coat of KBShimmer Clearly On Top gave the mani some extra shine.
