I nearly wore mine today, with a longish gathered skirt (hard to explain, I normally don't do skirts) and a longish cardi which went down below the jacket iyswim.
It looked really nice I think, but I chickened out as it really shows off my bump, and I prefer to wear a long coat I have, I don't really feel attractive being very pregnant 
Glad people liked theirs. I want to get the Zara one now!!
(ps know what you mean about the buttons, person who said that!)
