Outdoor wedding dress?

So I am planning an outdoor garden type wedding. However I'm a bit iffy on what the colors of my dress should be. I am in love with this dress:

I have contact the designer for pricing (btw, anyone know rana noman bridal charges?) and if it's outside my budget I would like to get a similar outfit made with same colors.

But I feel this outfit would be better suited to a hall venue wedding versus outdoor... Idk. Will this outfit look odd in a garden venue? What decor should I do? I'm going to be doing lots of lights on trees and stuff as well as flowers. I was thinking red and pink flowers, but would pink fit?

I'm just confused lol. Please give me your 2 cents on the idea!

Thanks:)
