Thank you for viewing. I received this as a gift and have only worn it once. There's no tag, but it's equivalent to a size 120 based on the actual measurements. Length: 39cm (from the top to the hem on the back) Width: 35cm (measured straight across under the armpits) *Measurements are taken flat. Please allow for some error. It's reversible and cute. Since it has been handled by someone else, please understand that it is a used item and only purchase if you are okay with that.
