If you're thinking what I am...don't. I am not advocating the buying and returning of a used garment, even though many, many girls out there do this. I just want to point out that the return policy at Dessy.com is really great--a full 30 days after you buy it!
Besides that, look at this dress. I like it for the color, but also for the silhouette. It's modest and flirty length are really sweet. At $208, it's not a bad dress. It's also something that could be worn again since it isn't overtly "bridesmaid" wear.
This is an Alfred Sung design.
Color: Seaside (other colors to choose from)
Also from the same website is this cute Trapezoid Dupioni clutch with jeweled clasp for only $24. I like that it's not the same color as the dress. This color is called "Dove."
