I must have about 15 "almost right" shades, but I'm still searching! This shade by Nina Ultra Pro comes very close -- either way, it's really pretty!
Indoors, bright cloudy daylight (no sun), near windows.
Outside, bright cloudy daylight (no sun).
Shaded cloudy daylight (no sun).
Overall I am LOVING this polish! I don't know if it's my skin tone setting off the rosiness of the polish or what but it's way prettier than I thought it would be just looking at the bottle! In the bottle it seems more brown/subdued. It's a great neutral and it's the closest I have found to Molly Ringwald's Breakfast Club shade (on my skin tone, I know polishes look different on everyone).
Where to buy? Sally's Beauty Supply for sure (online and in-store). Likely Amazon and eBay as well.
NB: I purchased this polish myself. I have NO affiliation whatsoever with the polish maker or websites discussed in this post.
