Rute, I agree with everyone else about the dress. Also, as someone who is large-chested, I will say that I sometimes find that neckline difficult to wear. I think that because the neckline is so high, it sometimes has the effect of making the chest look never-ending. Does that make sense? I do own items with high necklines, so I don't think it's always the case, but I do think it is something to look out for.
As for the blazer, I personally don't think that it's too long. My only critique is that when it is buttoned, the button seems to be pulling. It is difficult to tell if it's just a little tight, and maybe moving the button over slightly would solve the problem, or if it is being pulled by your chest from above. I think it looks great when it is worn unbuttoned.
