I purchased this from WEGO. It's a size M, but it runs small, so I'm listing it as a kids' size 150. ⚠️Please be sure to check the actual size measurements: Waist: Approximately 30.5cm Length: Approximately 41cm It has a lining to prevent see-through, but only on the back side. While it's not as white as when I first bought it, there are no major stains, so I think you'll be able to wear it cutely♪ I hope you like it.
