I have both Pink Opal and Rite of Spring and I am loving RoS two, three times more, and I have a tsp. of PO to go through! Nailpolish it'll become, most likely. Anyhoo, I love RoS because of the more evident yellow base - unique! - and the duochrome isn't as frosty as PO, which is annoying to me at times. The yellow base isn't like Spring Up of which you can't see much of the yellow because of the frostiness. I was afraid of looking jaundiced with it but I think it's okay, maybe the pink pearl does the trick (or I'm just talking myself into it, lol). I've found Lightscapade to be similar to the yellow base but much paler or subtle.
On me, Jete is not like Deckchair. Jete is described as a "sandy coral", and I think that "sandiness" sets it apart from Deckchair. In other words, Deckchair's more clear in its colour, where Jete seems to have a hint of beige (or something) in it. Also, Deckchair I find it frostier, or more reflective.
Corps-de-Ballet has been compared to VGV and Pink Clash, but I like it better than either and they've been longtime favourites of mine. VGV has a bit of brown to it which CdB doesn't, and Pink Clash is more glittery whereas CdB has more refined shimmer, and it's multicoloured! Not a must-have, but I couldn't take my eyes off of it.
I may end up getting Classical as 15-Minutes gives me Barbie lips, which look incredibly displaced on my asian face. I think it's the texture which does it. Classical will be easier to use with the lustre texture. I missed out on Pink Maribu so Danse might be mine, but my mind's been on Curtsy - I love my Pink Cabana but sometimes I want a toned-down version, and I think Curtsy would be it!
Sorry so long, but that's my 2 cents!
