Here are a few dress suggestions. All of the sellers I mentioned are legit. You will find trustworthy reviews for them. You just have to check out the Amazon sellers, because I can't say anything about them except for the reviews seem promising.
Most of these sellers (again, except Amazon) will make the dress according to your measurements, and you can change the color or minor things (e.g. request for sleeves to be added) most of the time.
Anything you happen to like?
