I am a bit over 5ft. 4 in. and I love that it comes down to mid knee.  I washed it and it did not shrink even though it is my favorite, 100 percent cotton material.  The dog design is bright and really cute.  I bought more of these with various themes for gifts because I think everyone will love this nightshirt.  Also, another must for me is it can't be see through.  At my age I need to cover-up but that does not mean I can't wear cute nightshirts, so I am happy it is not too light a cotton that it is see through.  This fit well but I really don't think anyone who takes much bigger than a large will be comfortable in it.  I got a large and it could fit an XL but I don't believe it will fit beyond the XL.  I weigh 139 lbs.
