I am 55 years old, 6' 1" at 235 lbs. My t-shirt length measured from the top of the collar to the bottom of the shirt is 29 1/2" long which hangs to my mid-derrier level.
I, personally, at my age do not wear tight-fitted shirts. I like them snug in the collar & the sleeves a little longer - just slightly above the elbows. The shirt runs slightly big even with broad shoulders. I bought a 2x, used a regular washing cycle & fully dried it on high. Fits perfectly now. After 5 months, the logo & shirt itself has not faded. Good quality and not made out of thin material. I purchased 2 more as gifts.
