I may not be built exactly like you, but I am similar enough that I believe I can give a helpful assessment. I'm short and "gifted" up top and know what it's like to have things not fit correctly. Please don't take anything I say as negative, because I'm talking about my own body too.

You've got to downplay the not-so-positives and play up your assets.
1. Something about those straps just ruins the look. To me, there is just too much "stuff" going on. It's distracting. When I was getting married, I had a vision of the dress I wanted. Dear lord, I tried on a few dresses like my vision and I looked like Dolly Parton in a Barbie dress on steroids.

It was just tooooooo much froof for a short well-endowed girl. I went for simpler lines and "lost" about 25 pounds in the process. I'm not saying #1 is a horrible dress, but it's not the best for you of those choices.
2. Of all the dresses, assuming you can get the proper size, this is the one I'd go with. It is
very flattering. It makes you look "narrower" and thus taller. It has lovely details, but less froof and that means you call attention to
yourself and not the dress. You don't want the dress to be the center of attention....YOU should be the center of attention. People should say how lovely you look in the dress, not what a pretty dress it is.....And there is a difference. #2 does all that. It's a great look for you.
3. If you go for this, I beg you, do not wear a sash. If you do, it will cut you in two visually. It will ruin the lines of the dress and make you look shorter and wider when there is NO need to. It's much more flattering without the sash. Plus, sashes are trendy and later you will look back and wonder why you even wore it. This dress is okay to me. Not great, not bad......Simple, but pretty. Looks more like a wedding dress than #4 or #5, but less like one than #1 or #2.
4. Again, if you get this one, lose the sash for the same reasons. But of all the dresses shown, this is the least flattering. The high neck just is not good for you. It seriously emphasizes your.....chest.

Looks like a prom dress.
5. Also looks like a prom dress. Something about the big flower bugs me, but that's just a personal issue. If you took it off, the dress would look funny. The top is flattering on you, but the bottom is meh. Compared to #2, I just can't put them in the same league.
6. Since I can't see this on you, it's harder to say, but I'll imagine it on me. With my arms and ample upstairs, cap sleeves are not often a good look. A lot of times, they give the impression the outfit is simply too small and that's not even the case. Unless this looks great on you in person, I'd skip it.
To summarize, I think #2 makes you look far and away better than any of the other dresses. It's a closeup pic, so you ought to look BIGGER to me, but you look smaller.

Your waist looks tinier and it plays up your curves. I know you love #1 and if your heart is set on it, then get it. But #1 and its ruched bodice aren't as good a look for your top half as #2's classic lines.
At any rate, have a wonderful wedding!
