Hey, so short answer - 9. :)
Slightly longer answer - you have a really great figure, from what we can see you're slim but curvy and that's the holy grail in shape land, the dress really suits you, you have lovely pale, clear skin, hell even your nails look great and coordinate perfectly with the dress and you accessorise (I'm English, I refuse to give in to the spell check and spell that with a z ;oP ) very nicely.
Why not a 10, well, we can only see part of you so I'm making assumptions about the rest and, aaargh, I SO hate clear plastic bra straps I really don't know how to tell you! They're as invisible as a full beard and just as attractive, have confidence in your figure and wear that sort of dress without a bra, as it was intended to be worn. I promise you don't need it, and I promise you'll look a billion times better - plastic bra straps have no place in your wardrobe, you're way better than that, be brave, you can do it! :)
That little issue aside you look gorgeous, be proud of yourself :)0

it would be easier to guess your weight if you gave us your height but i'd say you are in the high 130s or 140s kinda hard to tell tho cause its not a full body picture.0
