I like this dress. The fact that it has a higher neckline makes it OK for a larger chested lady IMO. It looks youthful, yet classy. You will have to see how it looks on you. If it doesn't fit well (i.e. creates a uniboob, pulls, or the hem is too short), then it is a no go. As for the color, I don't know how it would look in brown. It could end up looking cheap. You may want to stick with black instead. It will also look classier if you carry it with a more classic/structured evening bag and keep you accessories simple.
