Essie Cascade Cool is a very cool-toned, light-medium pink with a cream finish. It is a limited edition nail lacquer that retails for $8.00 and contains 0.5 oz.
Essie Cascade Cool Nail Lacquer ($8.00 for 0.46 fl. oz.) is described as a "creamy, sweet dusty pink." It's a light-medium cotton candy pink with blue undertones and a cream finish. Not quite Pepto pink, but it gives me similar vibes. You know, it's funny: MAC makes a LOT of the blue-based, cotton candy pinks in the world (and not just nail color); all of the closest shades to this are by MAC. MAC Saint Germain is slightly pinker, less cool-toned. MAC Vagabondage is a smidgen lighter. MAC Ice Cream Cake is a fraction darker. Zoya Rory is somewhat similar in color, but it has a very shimmery finish, so they aren't really dupes.
