BlackCarrot I am built like you by the sound of things and wore a very similar dress (by Jolie Moi through Next) as a wedding guest last year.
I felt great in it. It was flattering to my shape and as it was a hot day I didn't bother with anything over it. The angel sleeves covered my least favourite bit of my arms!
Go with your gut. I didn't check out all the recommendations but I did notice the Rixo link and had a quick look. Some of those were what I'd also wear to compliment my shape (as a short busty).
