Thanks everyone! I absolutely adore this dress - the alterations will be a pain because of the lining, but are alterations I've done before, so it's all goodie The fabrication is a linen blend and does not seem to wrinkle easily.
Mia, they had a skirt in the same floral fabric as the other dress - it did seem a bit stiff. I might not mind that if it makes the flared skirt stand out a bit (like how a crinoline would). I am not opposed to keeping both dresses and wearing one to the rehearsal dinner (DH is the best man) and one to the wedding.
Claire, this dress has a pretty waistband (the bottom part is straight while the top curves in the center) and the skirt flares out slightly with a single front pleat - it's still tacked closed in the photo.
Firecracker, I like the idea of adding another color for the topper. Firecracker and Suz, some people are adding a topper and changing shoes for the clambake, and some are changing completely. I like the idea of topper & shoe change best. I was thinking of wearing my Bella Vita Wow pumps (they should fit my surgery foot by then) and changing into the peep toe wedges you see in the photo.
Vicki, I am heading over to the Boden website to check out that cashmere topper. Thanks!
