I love all of these blushes for different reasons. Perfect Cheek (limited edition-sorry!) is a neutral matte blush that is great when you're in a hurry, it goes with any look! As you can see, this just accentuates my natural cheek color, which is why I love it so much. Simple, but classic.
If you can't find this anywhere, an alternative would be Blushbaby by MAC.
Next, Springsheen. Out of the three, probably my favorite. You have to have a light hand to apply it, but if you do it right, the effects are amazing. It has a bright pink undertone, with gold shimmer on top. Not chucky gold shimmer which I HATE. It just seems to blend into my skin perfectly.
(I applied it heavier in the picture so you could see it better.)
Lastly, Margin. This is another one that is very easy to overdo. If you're not careful, you'll end up like this:
Apply it lightly, enough said.
Same as Springsheen, it has gold shimmer (a little bit heavier because it's a frost), just with a brown base. Great for days when I'm missing the sun, and don't want to look like a vampire.
Hope this was helpful!
