A person with an above-average muscular build is always difficult to find good clothes. My main problem with shirts is that I can't fit my hands in them. This shirt is flexible enough to fit my arms and neck snugly and the bottom is not baggy around the waist. I'm 5ft 8" and between 205 and 215 pounds and the medium size fits well but complements my build very well. My arms are about 18 inches and my waist is 32. My chest is 44. Hope this helps!
