As no gender was specified, I assumed this shirt was sized for men.  I ordered both the small (which should have fit just right with a little extra room if mens) & the medium (my typical size in womans) to ensure at least one would be the correct size.  Upon receipt, I found the medium just fit (was expecting it to be looser, based on type of shirt).  Most likely the large would have been the size & fit I wanted.  Who would have known?  I was also disappointed to find the fabric was very stiff, not soft at all (not even after washing!!).  I had purchased this for a zombie walk (perfect backdrop for fake blood), & it did work for that.  I was planning to wear as a night shirt after, but it is not comfortable enough for that purpose (the ONLY long sleeve T-shirt I own that isnt).  I can say there was no shrinkage after washing, so that is a plus.
