I'm starting to see stacked heels creep back so I think they will definitely be hip in the fall. I personally can't wait because they are so much more comfortable to walk in
I think you're right about the stacked heels (but i don't know if i could go back to that). I wonder if more embellishment & ornamentation. I think maybe more urban jungle look. Looser construction, earthy tones and materials.
I think vests will be huge. They are already huge in London. They will be the new option for layering and moving away from shrugs, although I still expect shrugs to be around for a while.
