Yes, the forms are going for sure. Those photos are just pre-edited (before I lob off my head!). While I personally like the black jacket and grey skirt best, I've put on some weight and the "frumpy" look of the others is- because I'm frumpy looking at this weight!
I'll choose the plainest blouse I have, likely even a man's oxford.
It looks like it's going to be raining while I'm traveling, so a rain coat is probably going to conceal a lot of details from the waist to the neck.
