Black Cardigan Tank Top Ensemble M The size is unknown for both items as there are no tags, but I think they are around M. Please refer to the following measurements. ⚪ Cardigan Shoulder width: 42cm Width: 48cm Sleeve length: 24cm Length: 56cm The fabric is knit and slightly sheer. The material feels like polyester. ⚪ Tank Top Shoulder width: 32cm Width: 42cm Length: 53cm The material feels like it's mainly cotton. Please note that these are flat-lay, amateur measurements, so there may be some errors. The two items are not from the same manufacturer, but I have been wearing them together as a set. They have been stored at home for a long time. There appear to be no noticeable stains or pilling. If you understand that these are used items, please consider purchasing. Please be aware that they will be shipped folded compactly.
