Gel polish on natural nails.
I used Bluesky 504 as a base. For the french I used Bluesky 907 'Frozen Palace'. The blue glitter polish on one of the index nails is Bluesky BLZ49.
On the decorated nails I made diagonal gradient between 907 and qcm36 from the Cat Eye collection.
The fish is a stamped decal made using Bundle Monster BM-502. The palm is hand painted with acrylic paint.
