Here I've used two coats of $OPI I'm with Brad and a coat of $OPI It's Real 18K Gold top coat.
I'm with Brad is absolutely gorgeous and glowy. It was almost opaque in one coat and I really enjoyed using the old style $OPI brush, which is very long and skinny. I get so much better precision and control in application with that one!
The newer $OPI brushes are more like the pro-wide. I haven't compared them side by side, but I would not be surprised if they are in fact exactly the same now.
The sun really brings out the beautiful red shimmer in I'm with Brad. In low lighting it looks much darker and deeper - almost black.
