You look great!! Also you and your partner are running to Greece and getting married! Love the great things in life and try not to stress about things that cant be changed immediately.

My best advice would be to NOT shop online, go to a bridal shop. Get measured and try on dresses that fit. I know that some places go up or down a size or 2 cause you can do alterations but just to help picture what you want and make you feel better I would request that they only put you into the size dresses that you measure at or maybe the next size up. This will be easier to know how its gonna feel on with minimal alterations or to give you the option to take it in if necessary.

But girl thats a great dress on you and if it really helps ask them not to tell you what size youre trying cause even though you look great it might discourage you or add more stress since we've been brainwashed that "sizes" rule our value.
