I saw a few people wearing dresses like this when I was in the Vineyard a few weeks ago. I like it. It's very stylish looking. I saw them at Lord and Taylor last night, and I'm pretty sure they are super expensive.
But, they just look so easy to make. Knit top, elastic waistband, little skirt. I have an appointment at one today and then am off the rest of the day. I think I'm going to try to make one. I might even try to make the pocket if I'm feeling saucy.
