Front length: 84cm Width: 56cm Please consider that there may be some errors as this was measured by a amateur. Size is M. Color is close to light blue. I think there are no noticeable stains to the untrained eye. I wore it for one season and then stored it. I have washed it many times, so there is some wear and tear, such as loose threads. Please see image 5. Thank you. niko and... T-shirt top
