There is no fucking reason why a 5'1 110lb woman should need a medium while a 5'10 170lb man is also a medium

Title. <br><br>I'm 5'10 170lbs (17.6% body fat). Pretty average size<br><br>My girlfriend is 5'1 110lbs. She's tiny! <br><br>We both wear medium shirts. That's fucking ridiculous. <br><br>There is no reason for a 110lb person, or even a 170lb person, to fit a medium. <br><br>MEDIUM MEANS MIDDLE SIZE, NOT SMALL SIZE!!!
