I recently got a little sample version of Clinique's Blushing Blush Powder in "Aglow" in my stocking for Christmas, and I couldn't help but notice it looks a lot like e.l.f.'s Studio Blush in "Peachy Keen"!
Clinique's full-size blush in Aglow costs $20.00 while e.l.f.'s blush in Peachy Keen is only $3.00
As you can see in the swatch, Aglow is a little more gold and Peachy Keen is more of a lighter peach color but they both have the exact same shimmery finish.
The Clinique blush has a smoother texture, is more pigmented, and has a longer wear time while the e.l.f. blush is a tad chalky, requires some building, and wears off in about 3 hours.
But if you're looking to save $17.00 and don't mind the difference in fomula, definitely check out e.l.f.'s Studio Blush in Peachy Keen, there's absolutely no difference in color when its on your face!
