This is Serum No. 5 Poppy Fields (a mini):
I've had trouble remembering over the years if this was Poppy Field(s) singular or plural - somewhere along the line I got it in my head that it was singular. Actually I assume this is supposed to have that WWI connotation of the poppies in Flanders Fields, so yeah, plural. You can see it right on the bottom of the label in this picture if you look close.
Ooh, look at it over Chanel Taboo.
Re availability: not on S-No5's website. I think it may have been LE in the first place but I'm not sure of that. My guess is that it's not easily obtainable.
(If you're looking at the "fail" tag by any chance, and wondering if something is wrong with Poppy Fields, no, in this case it was MY fail. The first time I posted this it was with an entirely wrong swatch.)
