That's lovely and I don't think it's bridesmaidy unless the bridesmaids are wearing dark full-length dresses. I think it would look great styled as UrsulaBuffay suggests, too (and I do have style ). I just bought a Coast dress for a wedding myself - great fit and quality.
It's nice, though I have to say went to a wedding last weekend and the bridesmaid was wearing something quite similar in style and colour! That's just a co-incidence though, and otherwise I wouldn't think 'bridesmaid' when I saw it.
