First, I went for the neutrals. From thumb to pinkie, this picture shows Hidden Treasure on its own (excuse my stained nails...I didn't use base coat the other day and I am kicking myself for it), then over L.A. Colors Antique Rose, A Perfect 10 Talk Dirty, an unnamed Charlotte Russe polish, and Sally Girl white. For some reason I couldn't capture the effect of Hidden Treasure at all on those last two fingers...the flakies are subtle in real life, but you CAN see them. I promise. My favorite combo from these four is probably Hidden Treasure + Talk Dirty, though I also loved it over Antique Rose.
From left to right, this is Hidden Treasure over OPI Red My Fortune Cookie, an orange franken of mine, Nina Ultra Pro Like Butta, and Sally Hansen Lightening. My favorite of these is absolutely positively Red My Fortune Cookie. It's my favorite red anyway, but with Hidden Treasure on top it reminds me of one of those huge dragons in a parade...you know what I'm talking about? Hidden Treasure is also pretty subtle on the yellows, though again, not as subtle as in my pictures. And Lightening is NOT that green in real life - I think it looks icky in that picture.
From left to right, this is Zoya Ivanka, China Glaze Kiwi Cool-ada, Zoya Roxy, and Sally Hansen DVD. I really, really love all of these combinations, but if I had to pick a favorite it would probably be Hidden Treasure + Roxy.
Left to right: OPI My Private Jet (new version), Orly Prince Charming, and China Glaze For Audrey. Sorry for the dent in For Audrey...I happened to run into a piece of paper just before I took the picture. Oops. I also loved all of these, but my favorite is My Private Jet - the bronze and copper colors in Hidden Treasure complement the bronze flash in My Private Jet very nicely.
I know a lot of people don't like Sally Hansen Insta-Dri brushes. If you're one of those people, you probably won't or don't like the Complete Salon Manicure brushes either, because as far as I can tell they are exactly the same. However, I'm quite fond of those brushes, so I had no trouble with the brush in Hidden Treasure. It applied very nicely, and removed smoothly as well. My only problem with removal is that I ended up with bits and pieces of glitter on my fingers, which you can see in my pictures above if you look closely enough. It wasn't nearly as bad as most regular glitters, though, for which I was grateful.
I really wish I could've gotten another bottle of this beauty...I will still be watching for it, and maybe if I find another one or two or three I'll do a giveaway! If you'd like to see Hidden Treasure over a particular color, let me know in the comments - you can look at the list of polishes I own here on Google Docs.
