Bottega Veneta's 'Cassette' continues to headline our edit of this season's most desirable bags. Made in Italy using padded strips of leather to create a puffy silhouette, it unfastens to reveal a spacious interior with a zipped pocket. The chunky chain strap is made through a seven-step mechanical process that ensures it reaches the perfect length and is galvanized for a shiny finish - it's covered with a protective layer, too.
