I finally picked up Essie Jazz the other week! It has always been out of stock at my Ulta during B2G1 sales, but I found it at a beauty supply store.
Essie Jazz - 3 coats, which is not super awesome, but the formula is easy to work with.
Now, my go-to nude/underwear polish is Orly Country Club Khaki. I love it to bits. Here's a comparison:
Comparison: Essie Jazz and Orly Country Club Khaki - Orly CCK is a bit darker and also more opaque, needing only 2 coats.
I haven't decided if I should purge one of these. I shall defer the decision.
Happy Hump Day!
