Ok, so I'm going to dip my toe in the water and say that, unfortunately I agree that your biggest problem is that your bra fit isn't great, and I say this as someone who struggled for years in what I was sure was a 32DD and turned out to be a 30G/H (until I had a reduction).
I also think you have long legs and a short torso, and I suspect that before the pregnancy c-section weight gain you would have considered yourself an hourglass, knew how to dress for that, and are now struggling with the fact that between the boobs and the new stomach, you're having a hard time defining your waist.
I think you should try a pair of good jeans (one of the ones rec'd above) and a knit like the cardigan posted by a pp that comes down to your hipbone, untucked. And for what it's worth, I think bootleg or slim flares would be great for your shape.
I like the first dress, I agree the second looks to small at the moment. How would the green skirt look with a bulkier sweater or a tailored shirt?
As another unwanted aside, do you think you have diastasis recti? I did, post-pregnancy, and pilates and some physio got it sorted and I lost the stomach overhang. And how old is your baby? Are you currently breastfeeding?
