I agree that, from the description, Pink Buttercream sounds very like Victoria's Blush Pearlmatte, but with the addition of the periwinkle leaves. Pink Buttercream may win for me, since it is a tiny bit cheaper than the Archies Girls one.
I can't say I'm struck by the descriptions of any of the lipsticks, and I won't even contemplate buying such expensive lip balms when I have a ton of cheaper ones here already. I already have Transparent Teal pigment and I love it, but can't see me finishing my jar any time soon; the Pink glitter sounds interesting, though.
So for me, I'm thinking I might get both Pearlmattes, Pink Glitter, and (depending on swatches) Fancy Frosting, Mooncake and Eclair Paint Pots.
