There will be a little bit of shrinkage after the first wash. If you're not sure what size to get, the sizing chart below is accurate.
The width is taken from where on a regular t-shirt the distance across the chest would be measured from the bottom of each seam where the sleeves attach to the shirt. A handy trick would be to take the same measurement of your favourite t-shirt with a ruler or measuring tape, so you can choose your size with more confidence.
|Length (inches)||25 ⅞||26 ½||27 ⅛||27 ¾||28 ⅜|
|Width (inches)||15||16||17||18||19 ½|
