Out of the hundreds of water decals I own, there are these rainbow color patterns that reminds me of doilies. Well, usually doilies are white, these are rainbow. These are the style in HOT-164.
I love any HOT style's water decal. They have the best quality! Not too thick or too thin. The opacity of the images are just right.

Here are the polishes I used from left to right:
Sally Hansen Triple Strong Strengthener
Only 40729 Lollipop
Étude House Enamel Ting Gel Nails #14
Seche Vite Fast Dry Top Coat
So first I did 2 coats of the base colors. Note that the pink is a gel polish so I needed to use a UV light to cure it.
After the polishes are dried, just applied the decal on your nails! It's so simple!
