Indeed it is. Victoria Plum was actually in the filename but I didn't think it was her actual name for some reason. Victoria Plum is also an online retailer!
So, that just leaves pic #3 (girl in pink top). All I can find is various photos of her as stock images which can be purchased from different sites (the images generally have watermarks on them as per the pic above) but I'm hoping that either somebody recognizes her or is able to determine which model it is in the photos.
