I've never attended a Jewish wedding but I was told that modesty is key so most of my cocktail dresses were out of the question. I stumbled upon this very simple but sweet silk Ann Taylor dress, love the little rose details on the sash but now I have to choose between two colors, the plum berry (my fave) and the navy blue. Both colors are lovely but the plum berry is only available in a size 6 and the navy in a size 4 (my size). I would need to get the plum berry altered if I choose that one. Both dresses are the same price and style. Which to choose?
