Outfit for engagement photos

Hi all! I am trying to pick out a dress for our engagement shoot. I know the shape of this dress will flatter my figure. I'm not certain on the color because I'm very fair skinned (as in light reflecting of my legs could blind passers by), but there are other color options. I think it will look pretty and flowy in the park garden at dusk...
The floral garden we're going to:


I'm super excited 😊 with my pale skin, would you go with this dusty rose color? They also have a lavender, dark purple, or baby blue that are pretty...
