actually, in cart page may cart items in quote object.

$cart = mage::getmodel('checkout/cart')->getquote(); $items = $cart->getallvisibleitems(); foreach ($items $item){     $options = $item->getproductoptions();     $superattributes = $options['info_buyrequest']['super_attribute'];      if (!!$superattributes){         $attributeobjsize = mage::getmodel('eav/config')->getattribute(mage_catalog_model_product::entity,'size_chart');         $attributeobjsizeid = $attributeobjsize->getattributeid();          foreach ($superattributes $code=>$superattribute){             if ($attributeobjsizeid == $code){                 $sizecode = $superattribute;                 $sizelabel = $attributeobjsize->getsource()->getoptiontext($sizecode);             }         }     } } 

the $sizelabel should want have. hope works.
