This review is for Essie's Borrowed and Blue, a very pale blue (not baby blue, but Easter/Spring/Summer gorgeous blue that makes your tan pop!)
This polish is gorgeous. It's not too gray, not too white, not too blue. The pigment is well-mixed, does not go on streaky, had no trouble with bubbles. This is an OPAQUE color by Essie. Two coats is more than enough for coverage. Add a self-leveling top coat such as Seche Vite and your nails will look great for a relatively long time. No chipping and came off very easily with acetone--I think I was able to get away with using only one cotton ball to remove! It does not stain your nails (there isn't really enough pigment for that) and it's appropriate for work, beach, interview, you name it. If you have a tan, this polish will really pop!
Highly recommended.
