Great shots. SUCH a shame the colours they've used on both covers just don't work - there's not enough contrast, they don't pop enough or compliment the images well. The warmer red and orange tones from the dress on the first cover would have been lovely instead of green.
Interestingly, I think the last time we saw green cover lines on US Vogue was back in 2009 with Cameron Diaz on the cover. It's pretty uncommon, I remember reading somewhere that green writing doesn't perform that well on the newsstand - I can understand why.
Nice images though, and it's good to see a new and unexpected face!
