I love all your enthusiastic replies, thank you so much everyone!!
Okay, update: I saw it in the shop today, there was only one left, not my size, so unfortunately I couldn't try it on. It was on the mannequin and looked beautiful, yet the fabric was a little less substantial than in the picture. And it was 100% linen... For that alone I'd be very hesitant, because of the wrinkling factor + as Aunty pointed out linen sometimes doesn't look very flattering from behind;-)
I would really, really loved to have tried it on though. I think I'm tall enough to pull it off and this style is just so right! The perfection combination of retro, elegant, dressy but not too evening-y etc.
Lavinia: thanks for the link, it's nice, but I prefer the wide legs of this one.
Laura: oooh wow!! I wish I could have seen you in that one, it sounds divine! (and if only this one was a wool blend)
Joy: I almost fell off my chair laughing, now I'm imagining all sorts of scenarios:-)))
Julie: you're right!! I hadn't realised, it is very Charlie's Angels (makes me love it even more). And absolutely, I promise!
Oh well, fingers crossed I can find something similar...
