It&#x27;s not so much &quot;precisely&quot; as &quot;not ridiculously wrong&quot;. The difference between &quot;slightly big&quot; and &quot;tent&quot; isn&#x27;t much, considering there is practically no objective basis to kids&#x27; sizings, which are basically the intended age with no consideration of variations in age &amp; growth; the sizes do not reflect an actual size.
