HI this listing is for the OP Pacific Sunwear Shirt.  It measures 22 inches from pit to pit.  And it measures about 30 inches long.  This shirt is an authentic vintage shirt from the 80s.  It is striped with the pink purple white and mint green.  The colors are really nice in person.  The palm trees add a tropical fun beach vibe.  It is a popover / polo type shirt.  It is a lightweight shirt, not a heavy fabric and not see through.  Great for spring break or summer.  Hard to find something like this, one of a kind look!  This comes from a smoke free home, thanks for looking!
