And the first has a delicious hint of soap opera that makes me love it!
But seriously, there are some great dresses out there in Navy Blue and if you have free reign then there are so many options. Like, so many.
Here are some tips that might help in choosing something to hide your "fat arms" (website's words) and tip 5 (a shawl, jacket, etc.) was one I would have recommended myself if you are very conscious of them. I say this because that doesn't limit your dress options - a lot of bridesmaid dresses don't have sleeves, so if you can get a good style / colour match with an accessory that hides your arms, then you have more choice!
