My mini haul, with the Hello Kitty toe separators from the set serving as backdrop: Kitty White, Let's Be Friends, Charmmy & Sugar, Starry-Eyed for Dear Daniel.
Kitty White is a straightforward white flecked shimmer, which yes, I probably do have at least a half dozen other versions of, but it's so fresh looking and reminds me of snow and I don't regret buying it. This swatch is three coats, and you can still see some visible nail line at some angles.
I wasn't sure how opaque Starry-Eyed for Dear Daniel would be, so I left Kitty White on all but my index finger as a base. Turns out this hot pink microglitter can be worn alone. Top nail below is three coats of Dear Daniel alone; other nails have two coats of Dear Daniel over Kitty White. I didn't add topcoat; this glitter is not especially bumpy.
I didn't have the attention span to swatch Let's Be Friends, the pale pink creme, on its own, and I was curious how its mate from the pedicure set, Charmmy & Sugar would layer, so I combined them, adding in Kitty White for more fun. Charmmy & Sugar has medium hex glitter in mostly hot pink but with a smattering of other colors in a shimmer packed sheer base. Top to bottom below: Let's Be Friends (3 coats), Charmmy & Sugar (2), Let's Be Friends topped with one coat of Charmmy, Let's Be Friends topped with one coat of Kitty White.
Unlike Dear Daniel, Charmmy is not opaque on its own at two coats, and doing three seemed like it would submerge the hex glitter too much, though at certain angles the shimmer reflects so much light that it pretty much obscures the nail line so maybe I would wear it alone.
I definitely will wear Charmmy layered, so I tried it over some different base colors. Top to bottom, one coat of Charmmy & Sugar over Kitty White, Starry-Eyed for Dear Daniel, Rimmel Picasilly Line (deep pink creme), and Wet 'n' Wild Black Creme. This is definitely a fun layering polish.
I bought the previous polishes at Sally Beauty, before I knew about or saw the set with the special edition shade Say Hello Kitty. Since it was a shimmer, I bought it, even though I'm sure I have something similar to this hot pink in my stash already (when don't I, really?) and won't likely use the bow-shaped Swarovski crystals included in the box.
I fancied I could see a bit of a shift in the shimmer in the bottle, but that didn't show on the nail. It's just a nice flecked shimmer. I think this was three coats, though my notes are unclear; apparently I was too excited to try layering it to pause and record the plain swatch properly.
And layer I did. Top to bottom: Say Hello alone, then topped with, respectively, one coat of Kitty White, one coat of Charmmy & Sugar, one coat of Starry-Eyed for Dear Daniel.
beautygeeks has a great long post with all the colors from this collection and swatch stick comparisons. I'm happy with the ones I got. It's a lot more pink than I tend to go for, but it is Hello Kitty, so that makes perfect sense.
