I found this dress in an antique shop one weekend while visiting my grandfather. The fit was a bit baggy, but I tried it with a thin belt to give it more of a silhouette. It’s a bit frayed at the edges, making me think it was longer at one point (you never know with vintage pieces). I’ve linked a few other loose flowey dresses above that would be great for this look. The boots are actually something I found on Amazon for extremely cheap. They very comfortable and easy to walk in, despite how high they are.
Also, the new Rogue One Trailer came out on Thursday (the film I’m working on). Check it out if you haven’t done so already!
