Actually, in cart page you may get cart items in quote object.

$cart = Mage::getModel('checkout/cart')->getQuote();
$items = $cart->getAllVisibleItems();
foreach ($items as $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 as $code=>$superAttribute){
            if ($attributeObjSizeId == $code){
                $sizeCode = $superAttribute;
                $sizeLabel = $attributeObjSize->getSource()->getOptionText($sizeCode);
            }
        }
    }
}

The $sizeLabel should be want you would like to have. Hope it works.
