I usually wear about a 2X & the robe they gave me covered me, but I would have been more comfy if it was bigger. I think the size of the robe was an XL, not sure if they had any bigger or not. I basically just had to wear it from the changing room to the massage room. Not far. If I had to have worn it for a long period of time, I probably would have asked for a larger one (if available - not sure).
