Got the SJP pack this afternoon. I've got all four on, two on each arm like lipstick swatches. First thoughts:
Stash: the most 'me' of the four; woody, very slightly balsamic, very slightly spicy. Would have liked a bit more 'punch' as the sillage seems poor but that could be partly because it's a rollerball. Will definitely wear this again though.
Lovely: yes it is. There's nothing to dislike about this; to criticise it would be like kicking a puppy. It's just a really pretty soft floral musk. I'm not sure I quite get the breathless hype but it is just...lovely. This will probably end up being a comforting CBA.
Lovely Sheer: too generic 'white floral' for me, I think, although I could imagine occasions when I'd wear it. It really, really reminds me of something else but I'm buggered if I know what. It's what I imagine a 'wedding' fragrance to be. I won't be wearing it at my wedding, though 
NYC: wow, this is red berries agogo - waaaaayyyyy too sweet and fruity for me. It smells like cheap shower gel imo. Disappointing. How the hell this is supposed to conjure up New York City is baffling; its more like slipping into a candyfloss coma on the 'It's A Small Small World' ride at Disneyland...
So, 1 winner, 1 very decent CBA, 1 yeah, maybe, sometimes and 1 dud. That's blind buying for ya
