Today, we have a comparison of two beautiful red shimmers OPI I'm Not Really A Waitress NL H08 and OPI An Affair in Red Square NL R53.
Index and Ring: OPI I'm Not Really a Waitress
Middle and Pinky: OPI An Affair in Red Square
Very similar aren't they? These two polishes are known to be dupey to each other. However, INRAW is a bit cooler with some pink tones while AAiRS leans towards a more neutral, true red. Also, the shimmer in AAiRS adds a special glow to the polish that INRAW doesn't have.
Different enough to own both?... I'd say no, but if you would like to get either one and couldn't decide between the two, I would go with An Affair in Red Square because of the prettier glow, despite the fact that I'm Not Really a Waitress is OPI's most popular red and is claimed to look good on all skin tones. Both of these are three coaters and are swatched with no top coat in the picture above. : )
