I've just listened and it is indeed very interesting, particularly the reference to avatars.
I'm not sure but either Bootstrap or Lekala offer an avatar image when you load your measurements.
FYI Last summer I bought a RTW button thru dress from the curvy range at ASOS, size 22. When it came it was HUUUUGE - more like a size 32, but the label most clearly said 22
I keep intending to take it apart and recut to fit me.
