Congrats on your wedding!
Now, this is not advice I normally give, but if you want to lose a few pounds very quickly, go very low carb. It should work to drop the weight fast, at least temporarily. Now, once you start eating normally again you'll probably gain most if not all of it back, but this is a once in a lifetime thing so you want to look your best :) Also keep your sodium intake very low, and do not drink any alcohol if possible in the next 2 weeks, those will reduce bloat.
My senior year of high school (which was almost 13 years ago LOL), I bought my prom dress in like February, then proceeded to gain like 10lbs in the next few months. I had developed a habit of going to get bagels and cream cheese with my BFF. Anyway, 3 or so weeks before prom in May, I tried on my dress and it wouldn't fit. So, I did the low low carb diet, and, lost like 10lbs and fit into the dress. I'm sure I gained it back afterwards, but I looked good that night in the dress :)
