Hey, take a good look at Ke Ai too - it's a beautiful sheer milky pink with the prettiest crystal shimmer. I know that sounds pretty dupable, but the shimmer and level of transparency and the tone of the pink all together are really special. It's beautiful and feminine on its own and I bet it'd be great over Sweet Pop too. It'd also be a great base for sparse glitters. It's the perfect ladylike foil for Flamingo, in particular.
If you're looking for more creme polishes, btw - I still am totally in love with all the cremes in the China Glaze Avant Garden collection from the spring. I get a TON of compliments when I wear Life is Rosy. Fade to Hue and Tarty for the Party are perfect dupes for polishes from Baking Beauties (and came out months before). It's my favorite nail polish collection of the year, so far, and makes me wish I had 10 arms like a Hindu goddess so I could wear all that paint! Sweet Pop is still in my top 5 nail polishes of the year so far, though!! MAC is the master for these sorts of soft, work-safe but unique colors.
I've got a new friend who is a photographer - if we get together, I'll make sure to get her to snap a few quickies with me in the sort of makeup I like best! For now, just think Tura Satana for the liner
