You need kids! Well, at least kids sizes.<p>I understand the desire for adults to have a shirt that fits, but I think that falls squarely in the bucket of &quot;nice to have&quot;. As a parent of a child that doesn&#x27;t fit <i>any</i> of the sizing charts, being able to predict what size of what brand will fit my kid would be a &quot;must have&quot;! Kids also tend to go through clothes a <i>lot</i> faster than adults, making the potential savings of getting a good fit far greater.
