In the bottle they look pretty similar, right? Take a look at a close up of the bottles below.
First up is Behind Closed Doors, notice the sparse magenta hex glitter. BCD also looks to have more glitter than Dorothy.
And here's Dorothy, the glitter looks so sparkly! So so far the only difference looks like the magenta glitter.
Here's the first coat, Dorothy on the left, BCD on the right.
2 coats. Interesting, Dorothy seems to have more glitter. It also seems to have a murky, muddy base where BCD has a more charcoal/black base.
3 coats looks to be opaque for Dorothy, but BCD needs 1 more.
I added another coat for Dorothy too.
Here's how the look in direct sunlight, no top coat. I would suggest a nice glossy one to even out the grittiness of the glitter.
So, what's the verdict? Although they have slight differences like glitter and base colour, in the end they pretty much look the same. If you have one, I wouldn't get the other. If I had to recommend one out of the 2, I would say get Dorothy. You need less coats for opacity, there is more glitter in each stroke and in the end it looks smoother than BCD. Wet N' Wilds brush was also too stiff for me, it is apart of the fast dry collection but I didn't notice it drying much quicker.
Which one do you prefer?
