So I finally got China Glaze Wagon Trail! So let's compare it to MAC Seriously Hip and OPI At Your Quebec & Call, shall we? I will probably do an on-finger comparison too, later, but for now we can compare photos.
China Glaze Wagon Trail, olive brown shimmer with pinpoint rainbow shimmer:
MAC Seriously Hip is a black jelly, though, with olive shimmer, whereas Wagon's has a brown tone added. So similar, but not exact:
OPI At Your Quebec & Call - much lighter, but same color as Seriously Hip, if you get me. Has the pinpoint rainbow shimmer, maybe not as much as China Glaze Wagon trail?
All in all my fave is still OPI At Your Quebec & Call.
