Posted on about.com: Top 10 "It" Bags An "It-Bag" is a designer handbag that is deemed the "must-have" item of the moment as a result of a combination of celebrity usage, clever marketing techniques, superior quality and their ability to represent the mood of the season. They are generally produced in limited edition quantities. These are the 10 "It" bags of seasons past and present, that we feel every handbag enthusiast should own, or at least know about. 1. Hermes Birkin The Hermès Birkin bag is named after the iconic actress Jane Birkin, who once had a highly public relationship with influential french singer, Serge Gainsbourg, to whom she bore a child (Charlotte Gainsbourg). The 'Birkin' is the symbol of ultimate luxury, due in part to its exposure on popular television shows such as 'Sex and the City'. An authentic 'Birkin' costs upwards of $6,000 and can have a waiting time of up to 2 years. 2. Chanel 2.55 This little classic will always be "in". It was born in 1955 (hence the name 2.55) after Coco Chanel decided she wanted a shoulder bag to free up her hands and is inspired py the quilting on Jockeys coats. Karl Lagerfeld released a second, updated version in 2006. 3. Chloe Paddington The Chloe Paddington was created by designer Phoebe Philo in 2005 and is considered to be the quintessential 'Boho-Chic' bag because of it's slouchy, unstructured shape and exposure by stars such as Kate Moss and Sienna Miller, who are known for their bohemian sense of style. A leather Paddington typically costs around $1,500. 4. Balenciaga 'City' Motorcycle Balenciaga's line of motorcycle-inspired handbags are created out of distressed goat leather, which is what gives them their unique, relaxed shape. The 'City' bag in particular, caused quite a stir after becoming the official handbag of choice for notorious fashionistas like Mary-Kate Olsen. The Balenciaga 'City' bag is not available online and retails for about $1,200. 5. Alexander McQueen Novak The Alexander McQueen Novak represents the structured shapes of Fall 2005 and was inspired by Kim Novak, a vintage-era starlet who appeared in Alfred Hitchcock films. It's original run consisted of a mere 200 bags, which caused mass hysteria among handbag lovers everywhere and elevated the bag into permanent "It" status. 6. Marc Jacobs Stam The Marc Jacobs 'Stam' is named after the designers close friend, Canadian Supermodel, Jessica Stam. The bag features quilting and gold hardware similar to that of classic quilted Chanel bags, but differentiates itself with it's relaxed look, gusseted frame and kiss-lock closure.

Fendi Spy The Fendi S/S 06 'Spy' Bag is priced starting at $2,100 and is a favorite of style stars like Hilary Duff and Linda Evangelista. It's notorious status is caused partly by it's enormous waiting list, which can last up to 3 years. 8. YSL Muse The Yves Saint Laurent muse is a status bag of the highest quality. Crafted out of the finest embossed leather, this oversize structured tote features expertly minimalist gold hardware and is often carried by celebrities such as Katie Holmes, Lindsay Lohan, Kate Moss and Jessica Alba.
