Though I ultimately loved the dress I selected for our wedding, making that choice was certainly an education in what looks good and what certainly doesn't.
Lesson #1: V necks are not flattering despite always assuming I'd wear one.
Lesson #2: Taffeta is heavy and overwhelms.
Lesson #3: Champagne gold dresses can be surprisingly flattering on a pale woman with pink undertones.
Lesson #4: Far too many designers are adding the "hurricane" to the skirts of ball gowns.
Prior to making the ultimate purchase though, I did seriously consider...
this v-neck dress (ultimately I came to the same conclusion about the neckline as mentioned above)...and this restrained mermaid (which was thisclose to being THE dress).
