E.L.F. BLUSH TICKLED PINK- The cheapest, yet very high quality drugstore blush. Comes in a variety of shades, including some with a beautiful sheen. I have several of these and find myself using them even over much more expensive blushes.
Need a cheaper alternative for NARS? ELF Cosmetics is the solution <3 Check the link! ^^ (dupe, cheap, 3$, save money, choose smart, blush, blushes, gaiety, luster, oasis, orgasm, sex appeal, angelika, albatross, sin)
ELF Blush Palette in Light- I personally haven't used them, but I have done much research and have found that many people adore the E.L.F blush palletes, which for four blushes made to fit your skin tone is an excellent value. Great if you're starting a collection!!
