Janet, I am going to be honest. Bare in mind that maybe I'm wrong, since I only have 2 pics to judge from.
I think dress in pic 1-2 is too tight. And even if you do fit in it, because your great figure allows you to, it doesn't do justice to your beauty. By pulling over the hips, it makes them look as if they should be narrower, when in fact this is precisely a lovely attribute of yours, something other women work out hard to get close to. Also, I'm not a fan of cap sleeves when they are stretched over the shoulder. You have strong, beautiful fit arms (as shown in #4, for example), but the sleeves' hem cut your arm at its widest part, just like when a midi stops mid-calf on an athlete. Finally, something bothers me in the dress bottom hem, the way it flips outward, like a pencil cut that changed it's mind on their way there but it was too late. A good cut would have allowed room for your curves and have penciled the pencil IMO.
By contrast, the dress in 3-4 suits you so much better, under every aspect. It celebrates you instead of trying to make you fit into a mould that isn't appropriate for you, it brings out your vibrant shape, yet it looks relaxed enough that you can entertain friends for an evening but I could see you kick off your shoes and go barefoot with equal pizzazz.
Oh - and your little blue jacket number is just adorable and so you! That blue is amazing on you.
