O.P.I. Designer De Better was one of the two shades I picked up from the Muppets Collection of 2011. This is a really cool champagne foil polish with tiny specks of a rusty-orange color. It's so hard to capture the sparkle in photos. It looks like a rose gold on the nail.
Here is a close-up that shows more of the rust colored shimmers.
I also have Warm & Fozzie from this collection. I wish I would have picked up Rainbow Connection because I tried an Ulta Dupe (Pinada-Yada-Yada) and the glitter is way too sparse. I also think Fresh Frog of Bel Air looks really unique and I love greens.
