Speaking with British Vogue at the Venice Film Festival — where she's promoting her new Gucci fragrance campaign in lieu of, you know, a film — Lively reminisced fondly about outfits past: "The only time I really felt a lot of regret is when it was something that I didn't want to wear, something somebody had made for me and it didn't turn out right. I never got to meet the designer and there was a lot lost in translation ... I just felt bad because it didn't look right on me, but I wore it anyway as I didn't want to hurt people's feelings." How kind! Care to take a look through our Blake Lively Look Book and guess which dress she's referring to?
