I purchased this at GAP. I wore it for two seasons, then washed it at home and stored it. The indicated size is XXS. Actual measurements are approximately 55 cm wide under the armpits and approximately 65 cm long. The length is measured from the bottom of the collar. Please allow for some error. The indicated size is small, but I usually wear a size S or M, so I think it's a larger design. Please check my profile before purchasing.
