I used Urban Outfitters Silver Holo (dupe for Color Club Harp on It) with Jade Vermelho Surreal on top for the stripes and Rescue Beauty Lounge Dead Calm with OPI DS Glamour on top for the blue base with Silver Holo dots.
Color Club Harp on It is still readily available right now, and Jade Vermelho Surreal goes in and out of stock on Llarowe and Ninja Polish. RBL Dead Calm and OPI DS Glamour are both discontinued and most likely going to be hard to find, but Glamour has some "dupes" being made more recently (one is Glamorous by Ninja Polish). Dead Calm is a dark blue creme, so there are probably some similar polishes out there.
