When wearing, you will need an undershirt as it is see-through. This is a piece of clothing that will be useful for the coming season! I am selling this because I haven't had the opportunity to wear it, even though it was given to me. Recently, shorter lengths are popular, but this one has a longer length! (lol) The size is M, but it's a roomy M. Please understand that this has been stored at home, and consider purchasing.
