I was interested in this polish when it came out, but not enough to purchase it at full price ($23 on the Lynnderella ebay store). However, I saw it on a blog sale last month for much less, so I decided to just nab it and give it a whirl.
FYI, I think you can message Paul (Lynn's brother, who runs the Ebay store) to set up a custom listing for polishes you are interested in. Also, if you are in Canada, make sure to contact Paul before you buy re: shipping, as I have read that one Canadian buyer was hit with ridiculous brokerage fees from UPS.
Here are some combos I tried with A Neutral Party:
Lynnderella A Neutral Party over Essie Don't Sweater It - Not loving this combination
Lynnderella A Neutral Party over SH CSM Fedora - Or this one, really
Lynnderella A Neutral Party over OPI Samoan Sand - I like this one the best out of the three I tried, but not blown away :(
I'm not in love with it in any of these combinations, unfortunately. I do think the shimmer is amazing, though! Any suggestions for layering, or should I cast it off to my swap drawer?
