Birkin vs Kelly: Full Hermès comparison guide

French fashion house Hermès is home to two of the world’s most coveted luxury bags: the Birkin and the Kelly. While they share a common heritage, each design reflects a different expression of Hermès’ artistry — the Birkin is relaxed and contemporary, while the Kelly is poised and polished. This guide explores the origins, style and impeccable craftsmanship of both bags, helping you to decide which icon best suits your collection.

The origin of the Birkin and the Kelly

Introduced in 1935, the Kelly predates the Birkin. Originally called the Sac à Dépêches, the bag was later renamed the Kelly after Princess Grace Kelly of Monaco used the bag to shield her pregnancy bump from the paparazzi.

The Birkin launched later in 1984, following a chance encounter on a flight between actress Jane Birkin and the then Hermès CEO, Jean-Louis Dumas. Birkin shared that she hadn’t been able to find a practical yet elegant handbag, which inspired Dumas to sketch out what became one of the most sought-after bags in history — the sleek, spacious Birkin bag.

The origins of both bags reflect the style they became known for — the Kelly is associated with old-school glamour and feminine elegance, while the Birkin provides a chic solution for storing your everyday essentials.

How are both Hermès bags made?

Every Birkin and Kelly bag is meticulously handcrafted by a single artisan and can take up to 40 hours to produce. Though each Hermès bag may differ in history and style, they both encapsulate the high-quality craftsmanship that underpins the French luxury house.

Both bags utilise the brand’s signature saddle stitching, which is known for its precision and can't be recreated on a machine.

The Kelly is made in two distinct styles — the Sellier and the Retourne. The stitching and edges differ between these styles, with the Sellier’s visible, exterior-stitched seams creating stronger edges in comparison to the Retourne’s interior-stitched seams, which make for a softer silhouette.

Since its initial design, the Kelly has been produced in these two different styles. The Birkin was originally only made in the Retourne style, giving it a more relaxed look. The Sellier version of the Birkin was introduced in 2014, debuting initially as a limited-edition release.

What differentiates their design?

Shape

The Birkin has a relaxed, slouchy silhouette, known for its spacious interior. This contrasts with the more trapezoidal shape of the Kelly, which has crisp lines and a ruler-straight top.

These differences in shape give the Birkin bag a more expansive and modern feel, while a Kelly bag evokes structured elegance and a ladylike aesthetic.

Straps and closure mechanisms

The handles are a key distinction between these two Hermès icons. The two structured top handles of the Birkin mean the bag can be carried by hand or in the crook of the arm. The Kelly, by contrast, features a single top handle, swivelling 'touret' and a detachable shoulder strap, which enables the bag to either be carried by hand, on the shoulder or in a cross-body style.

The hands-free practicality the Kelly offers creates a more versatile bag — though its single handle means the bag must typically be carried with the front flap securely closed. This differs from the Birkin, which can instead be worn open or closed. Favoured by those looking for a practical, everyday bag, the Birkin offers a more accessible feel in comparison to the refined aesthetic of the Kelly.

Leather and colours

Each bag is made with premium leathers or skins, with the most sought-after leathers including Togo, Epsom, Clemence and Swift. Softer leathers like Clemence can be a common choice for Retourne Kellys or Birkins, while the more structured Epsom leather is a favoured option for Sellier Kellys or Birkins.

Both Hermès bags are rendered in a myriad of different shades — from classic colours like Black and Etoupe to vibrant hues such as Rose Confetti and Vert Criquet. The designs also offer the same hardware options, available in gold, permabrass and palladium, alongside limited editions including rose-gold and diamond-studded.

Sizes

Both handbags are produced in a range of sizes. Birkin bags typically offer 20, 25, 30, 35 and 40cm options. Larger iterations, such as the Birkin Haut au Courroies (HAC) 50, are favoured for travel, while the Hermès Birkin 25 is coveted for its diminutive size —often referred to as the ‘Baby Birkin’. In November 2025, a Himalaya Niloticus Crocodile Birkin 25 with 18k white & gold diamond hardware sold for HK$3.6 million at Christie’s, making it the most expensive Himalaya Birkin bag sold at auction.

Kelly bags range from a (rare) 50cm option to a 20cm one. The Hermès Kelly 25 is one of the most versatile iterations — spacious enough for everyday use while still maintaining a compact size.

Mini versions of the bag also remain popular — the Hermès Kelly Pochette was introduced in 2004 as part of Jean Paul Gaultier’s first collection for Hermès and has become one of the house’s most sought-after clutches.

How much does each bag cost?

Both the Kelly and the Birkin are quota bags, with clients often restricted on how many they can purchase each year, as demand exceeds supply. This rarity impacts price, with Kellys and Birkins typically having long customer waiting lists.

At Hermès boutiques, prices typically begin in the five-figure range, increasing significantly for larger sizes, exotics or diamond hardware. Prices can vary further within the secondary market.

Investment potential

Alongside being an iconic addition to your collection, the Birkin and the Kelly are strong investment pieces. Their enduring popularity, limited availability and high resale value mean they have proved particularly resilient within the luxury investment market.

As with purchasing at a Hermès boutique, price is determined by a range of factors including colour and size. Discontinued materials or exotics such as crocodile or ostrich can also increase value, although the timeless appeal of classic colours makes them coveted investment pieces as well.

Limited editions often have a higher investment potential, with a rare Rainy Days Faubourg Birkin 20 selling for $215,900 at Christie’s in 2025. It can also be advantageous if a bag comes with its original box, dust bag and other accessories, as well as if the design is strongly associated with a renowned creative director, such as Jean Paul Gaultier.

The Birkin or the Kelly — which should I choose?

The Birkin offers laid-back elegance, with its spacious interior and open-top silhouette having the advantage of easy access for a wearer who is on-the-go. The more structured and feminine aesthetic of the Kelly is instead well-suited for formal events and elegant evening wear.

Alongside space and silhouette, another key consideration is how you wish to wear your bag. If the versatility of a shoulder strap suits your styling, the Kelly may be your preferred option.

Whether the Hollywood glamour of the Kelly draws you in or you favour the practical yet chic silhouette of the Birkin, both bags’ artisanal, handcrafted designs make them timeless icons of the French luxury house.
