The Kelly is Hermès at its most disciplined. Where the Birkin says "I have a bag," the Kelly says "I have taste." Choosing the right Kelly size is a decision about how you want to be seen, how much you actually carry, and — critically — whether you want the crisp Sellier silhouette or the softer Retourné.
This guide covers the three most-produced Kelly sizes (25, 28, 32), how they wear, what fits, how their resale differs, and how to think about Sellier versus Retourné within each size. Read this before your next boutique visit.

Kelly 25 — the modern favorite
What fits
A Kelly 25 comfortably holds a phone, small wallet, keys, sunglasses, lipstick, and a compact essentials pouch. It will not fit a laptop of any size. It will not fit a full-size water bottle. It's an essentials-only bag, designed for evening and refined daytime use.
How it wears
The Kelly 25 is the most versatile-carry Kelly. Handheld by the top handle, in the crook of the arm, or cross-body via the shoulder strap — all three positions work naturally at this size. The cross-body wear is particularly flattering because the small bag doesn't overwhelm the body line.
Sellier or Retourné?
Both are excellent in the 25 but read very differently. Sellier 25 (typically in Epsom or box calf) has a jewel-box quality — small, structured, formal. Retourné 25 (typically in Togo or Swift) is softer, slightly more casual, and slightly harder to shape-preserve because the small size means the panels are already quite tight.
Who it's for
- Evening and refined daytime wear
- Petite frames — the 25 flatters small statures beautifully
- Collectors adding to an existing bag collection (rarely a first-and-only choice)
- Anyone wanting to wear the Kelly cross-body regularly
Resale characteristics
The Kelly 25 has been the most-appreciated Kelly size over the past decade. Small bags have trended dramatically, and the Kelly 25 combines that trend with limited production quantities. Popular configurations (Sellier Epsom in Noir, Etoupe, Gold; Retourné Togo in similar neutrals) frequently resell at 40-70% above retail.

Kelly 28 — the definitive Kelly
What fits
The 28 is the practical Kelly. It holds a phone, wallet, keys, sunglasses, small essentials pouch, and a slim book. A 10-inch tablet will fit; a laptop generally won't. It's the everyday Kelly for someone who carries essentials plus a small extra.
How it wears
Handheld or via the shoulder strap — the 28 is the size that most clearly balances the two carry modes. Handheld, it reads as elegant. Cross-body, it's proportional without being dominant. This is the size most collectors picture when they think "Kelly."
Sellier or Retourné?
At the 28, Sellier and Retourné offer distinctly different aesthetics. Sellier 28 (Epsom or box calf) is the most formal Kelly available in a practical size — think business meetings, formal evenings, structured occasions. Retourné 28 (Togo, Clemence) is softer and reads as sophisticated but everyday. If you own only one Kelly and it's a 28, most collectors advise Retourné for versatility.
Who it's for
- First-time Kelly buyers seeking the definitive silhouette
- Daily carry with practical capacity
- Work-appropriate but not oversized
- Collectors adding "the" Kelly to a collection
Resale characteristics
Broadest demand of any Kelly size. Resale prices in popular configurations run 15-35% above retail. The 28 is the most liquid Kelly — you can find buyers at fair prices quickly.

Kelly 32 — the working Kelly
What fits
The 32 holds a phone, wallet, keys, essentials pouch, tablet or slim laptop, small book, and a compact water bottle. It's the practical work Kelly — enough capacity for a professional day, not so large that it looks like a briefcase.
How it wears
Handheld primarily. Shoulder strap works but the bag's size becomes noticeable on smaller frames. The 32 reads as professional and mature — it's the Kelly for someone using the bag as a working tool rather than an accessory.
Sellier or Retourné?
At the 32, Sellier is where the Kelly's structured heritage most powerfully expresses itself. Sellier 32 Epsom is a legitimate briefcase alternative — sharp, formal, and beautifully professional. Retourné 32 is softer and more casual, and works better for weekend or travel use than office use.
Who it's for
- Professionals who want to elevate their working bag
- Taller frames — the 32 balances better on 5'6"+ heights
- Collectors adding a "work Kelly" to a collection that already has smaller ones
- Anyone using the Kelly as their primary daily carry with laptop or tablet
Resale characteristics
Softest of the three sizes on resale. The 32 has fallen slightly out of fashion as smaller bags have trended. Well-maintained pieces in classic configurations (Sellier Epsom Noir with palladium) still hold value well, but expect prices closer to retail than above it.

Sellier versus Retourné: a size-by-size framework
Kelly 25
- Sellier 25: Best for pure evening use. The jewel-box quality is unmatched.
- Retourné 25: Best for versatile daytime-to-evening. The softer construction reads as more casual.
- Recommendation: If it's your first Kelly, Retourné. If it's your second or third, Sellier makes a strong collector piece.
Kelly 28
- Sellier 28: The most formal Kelly available in a practical size. Business and formal occasions.
- Retourné 28: The versatile everyday Kelly. Works from morning meetings to evening events.
- Recommendation: If it's your first Kelly, Retourné for versatility. If you specifically want a formal Kelly, Sellier.
Kelly 32
- Sellier 32: The professional Kelly. Excellent alternative to a briefcase for those in leadership positions.
- Retourné 32: Weekend or travel Kelly. More casual than Sellier at this size.
- Recommendation: Sellier at the 32 tends to be the more distinctive choice.

Expert tip
When your SA offers you a Kelly, they'll often propose one specific size, leather, and construction. Ask what else is available or coming — you're within your rights to decline and wait for a configuration that suits you. The Kelly is a decade-plus decision. Don't accept a size that doesn't fit your life just because it's the one being offered today.
Kelly versus Birkin
If you're deciding between a Kelly and a Birkin, see our definitive Birkin vs. Kelly comparison. Short version: the Kelly reads as more refined and formal, the Birkin as more versatile and casual. The Kelly's single top handle and structured silhouette make it more distinctive. The Birkin's twin handles and open top make it more practical for daily use.
The bottom line
There's no single best Kelly size, but there is a best Kelly for you.
- The 25 is refined, trending, and the best long-term investment — but limited in capacity.
- The 28 is the definitive Kelly and the safest first choice — versatile and liquid.
- The 32 is the working Kelly — practical, professional, and often overlooked.
Combined with Sellier or Retourné construction, you have six meaningful Kelly configurations. Choose the one that fits your life, not the one that fits the moment. See our Kelly storage guide to set your bag up correctly from day one, or the Hermès brand hub for the complete care ecosystem.
