Just discovered a cool blog teeming with resources for brides. Everything from venues to styling, and a ton of other useful things as well. It's British-centric, so most Americans will find the site a treasure trove of ideas. You can check it out at www.OMGimGettingMarried.com
There was an article posted about matching your cake to your bridal gown. I attached a few of my favorites here. Though, there are no gown shots, the idea is that you can match via color, texture, banding, and embellishment.
