This is a BUBBLES bustier. I tried it on, but it didn't fit my chest, so I'm selling it. Length: Approximately 18cm at the shortest point, 22cm at the longest point. Width: Approximately 39cm, excluding the elasticated part. Measurements are taken flat. I'm guessing it's around a B cup, but please use the measurements as a reference. Since I tried it on, I've listed it as "Like new."
