This is a Sea New York dress. It's a bit hard to see, but the striped sections have different fabric, making it a detailed piece. There's no lining, but it doesn't seem like it will be see-through. ★Size 2 Length: 80cm, Pit to Pit: 43cm, Sleeve Length: 57cm (Please allow for slight variations) I can't find the material tag, but I think the shop staff said it was silk, and it feels like silk too. ★Condition I've worn it once, and it's almost like new. There are a few wrinkles from storage.
