I am probably a true size 6, but I know AK runs large so I ordered the 4. And even that is too big, I really need the 2. But I'm not going to exchange this dress, I'm returning it. It's just not flattering. It is a little too long (and I'm 5/7) and the way the belt sits is doesn't flatter a tall, think figure. The material and color are stunning and I'm sure this looks better on a different figure which is why I'm giving it a 4. It's telling me I can only get a partial refund...I truly hope that only means that the shipping won't be returned because I'm sending it back the same way it arrived, tags, bagged and all. I'll update you and let you know how the return goes.
