I am 56 - 225 pounds and a size x-Large it fits me good theres a catch am heavy set yes but am a Size B in bras and a 41 inch chest so it fits not big not small either .. but if I had big breast and heavy set I would order a XXL.  I order different colors  of this item.. so you might see my review about it.. I don't want to be writing in all of them its like 4 or 5 colors I order..
