This robe definitely runs small. A am usually a medium/large (because I have a larger chest) and I ordered an XL. And the XL is still a bit to small. I about 5 3 and the XL comes to about mid thigh on me. So if you have a longer torso it will be real short.
But I like really the material, it is light weight and soft. Great for warmer weather. And the silk pattern part is beautiful.
