Saint Laurent's Envelope bag is an instantly recognisable silhouette; with this iteration, the Parisian brand demonstrates that a subtle change can make a big aesthetic difference. Switching out shiny hardware for a luxe matte version in a matching colour, the aura of the piece takes on a new form of luxe, romantic allure.

SAINT LAURENT's 'Kate' shoulder bag is a mainstay in the Parisian brand's collections - this version has a slim, '90s-style shape. Made in Italy from smooth leather, it has a delicate chain strap and is embellished with the house's tassel-tipped monogram plaque.

Saint Laurent Paris is the rebranded version of the house of Yves Saint Laurent with creative director Hedi Slimane at the helm. This versatile shoulder bag is inspired by the artist, A.M. Some bags will simply never go out of style, and SAINT LAURENT's 'Sunset' design is undoubtedly one of them. Adorned with the original 'YSL' logo plaque from the '60s, it's been made in Italy from croc-effect glossed-leather and has an elegant chain strap.

The Solferino www.saintlaurentbagsale.com bag, a brand-new addition to the Saint Laurent house last fall, takes some direction from the traditional satchel with its boxy, functional design. It has an understated exterior, its foldover flap fastened by a large YSL logo plaque. The first YSL Uptown bags were released during the reign of Pilati, all the way back in 2007. The most recent iteration of the Uptown bag is very different, however.

The signature gold chain hardware makes the collection practical and stylish and takes its name from the French word for link. And here's the thing: you can bet it will "link" all your outfits together. Next came the Hedi Slimane era, which started off slow and subtle with the Duffle bag. While under Slimane, Kering chose to drop the Yves from the name of the brand, Slimane Saint Laurent Bag Sale bags started to celebrate the YSL logo, especially in accessories.
