Loved the post, here&#x27;s a feature request for you:<p>I organize an annual conference [1]. All of our attendees get a free tshirt. We purchase all of our tees from a single manufacturer (say American Apparel) and let the attendee tell us the size they want before we finalize the order.<p>The problem is that attendees often don&#x27;t know what size will fit them, and sometimes guess wrong and end up with a poor fit. Anything you could offer us to help here?<p>[1] <a href="http:&#x2F;&#x2F;2016.cascadiajs.com" rel="nofollow">http:&#x2F;&#x2F;2016.cascadiajs.com</a>
