I saw the nail card of Mash Up today, but they'd already sold out of everything except the pale blue and the metallic purple. That's OK, because I can get a better price for all of them online and I pretty much want them all, except for the purple and pink, but will probably wind up with them all, because they get discounted when you buy the whole set, frequently.
Sparkling Garbage looked amazing. So did the neon orange, which leans quite pink - it's just this side of neon coral, rather than straight neon orange. Light blue is so gorgeous with the blue/purple shimmer. The plum looked like it could use more depth and richness of color on the nail card, but i think it will look better on full nails - it's not a duochrome, though, which I'd been hoping for. There's going to be a similar color for Fall in the Surreal collection, so maybe that one will be a little more dramatic?
Thankfully I've used all of mine, except for Heroine np, which is coming up next. I only did the dark blue Orly Hope and Freedom Fest for a test, using it as a dark base with a teal glitter ombre tip - that was nice, but I was feeling a little meh about it for a full nail, it's got a dusty quality that was a little too "blue jeans" for my spring taste.
It's hard to narrow down the absolute winners, but based on the ones I couldn't control myself from using multiple times, rather than going for an unused one, the white Orly glitter in the translucent white jelly base (LOOOOOVE), CG Dandy Lyin' Around (the white shimmer!!), CG Mimosas Before Manis and the CG Avant Garden bright red, which is a perfect match with Ronnie Red and Love Goddess.
I saw them today in person and I was totally underwhelmed, based on the nail swatch card. The black was the only one that remotely grabbed my eye, but not that thrilling, really.
Did you also ask about the Texture collection? I bought the blue, orange and reddish rose (because those were the ones I was least sure about, since the store allowed returns just in case. The texture is SO CUTE. It's mostly matte, but with tiiiiiny glossy undertone bits glinting through. I like 2 coats, but you could definitely do one coat and have a more glossy effect with just a hint of rough texture. With two coats, the texture is very deceptive - you might not notice it on first glance, but then on the next glance it totally reads. I like how subtle and sophisticated it is, combined with the cute bright colors. I'm going to wind up getting them all, since I only bought my least wanted today and I love them. I have a manicure with Ablaze on thumb and pinkies, and orange > rose > blue texture on the middle fingers. Very cute - I think I will do this combo more than once through the summer and then replace Ablaze with a black polish and keep doing this in the fall.
