Two coveted small bags
The Mini Kelly and Constance 18 are among the most sought-after small bags Hermes makes, both grail pieces for lovers of petite, elegant crossbody bags. Each combines the prestige of an iconic design with the wearability and charm of a small size, driving intense demand. Choosing between them is a wonderful dilemma, as both are exquisite, coveted bags that offer jewel-like elegance in a wearable form.
The decision comes down to the differences in their shape, capacity, style and feel, as well as personal preference for the Kelly’s structured silhouette or the Constance’s distinctive H-clasp design. Understanding these differences helps you choose the small grail that best suits your taste, as our Kelly market index explores regarding demand.
The Mini Kelly
The Mini Kelly, at around 20 centimetres, is a miniature version of the iconic Kelly, complete with its structured silhouette, single handle, flap closure and shoulder strap. It has become one of the most coveted bags in the entire market, prized for its adorable proportions and its faithful rendering of the Kelly design in miniature. The Mini Kelly is a jewel-like crossbody statement, intensely desired and often difficult to obtain.
Its structured Kelly shape, complete with the recognisable design elements, gives the Mini Kelly a refined elegance in a petite form. As a small crossbody, it offers hands-free wearability with grail status, making it one of the most desirable small bags available, as our Kelly guide details.
The Constance 18
The Constance 18, at around 18 centimetres, is the classic, most popular size of the Constance, featuring the iconic H-clasp, sleek silhouette and adjustable shoulder strap. It is a coveted small bag, prized for its elegant, distinctive design and its versatility as a crossbody or shoulder bag. The Constance 18 combines the prestige of the design with the wearability of a small size, making it a grail piece in its own right.
Its sleek, structured shape and the bold H-clasp give the Constance 18 a distinctive, sophisticated character. As a small crossbody, it offers hands-free elegance and everyday versatility, and its iconic clasp makes it instantly recognisable, as our Constance closure guide explores.
Size and capacity
In size, the Mini Kelly at around 20cm and the Constance 18 at around 18cm are both petite, with the Mini Kelly slightly larger. Both have modest capacities suited to essentials – phone, cards, keys and a few small items – rather than a great deal. The Constance 18’s sleek shape and the Mini Kelly’s structured form each accommodate essentials in their own way, with capacities that are broadly comparable and both limited by their small size.
For both bags, the small capacity is a consideration, suiting minimalist carriers who prize the petite, jewel-like elegance over practicality. Neither is a bag for carrying a lot, so those needing more space should consider larger sizes, while those who love small bags will find both accommodate essentials charmingly, as our dimensions chart details.
Style and character
The clearest differences lie in style and character. The Mini Kelly offers the structured, classic Kelly silhouette in miniature, refined and timeless, while the Constance 18 offers a sleek, distinctive design defined by its bold H-clasp, modern and elegant. The Kelly reads as a classic, structured statement, while the Constance reads as a sleek, distinctive one, appealing to different tastes.
Your preference for the Mini Kelly’s classic, structured Kelly charm or the Constance 18’s sleek, H-clasp distinctiveness is often the deciding factor. Both are exquisite and coveted, but they offer different aesthetics, with the Kelly leaning classic-refined and the Constance leaning sleek-modern, as our styles guide explores.

Which to choose
Choosing between the Mini Kelly and Constance 18 comes down to your taste. Choose the Mini Kelly if you love the classic, structured Kelly silhouette in an adorable miniature form; choose the Constance 18 if you love the sleek, distinctive design and bold H-clasp. Both are coveted small crossbody grails with similar petite capacities, so the decision rests on which iconic design speaks to you more – the timeless Kelly or the distinctive Constance.
Wearability compared
Both bags offer excellent wearability as small crossbody pieces, with shoulder straps allowing hands-free carrying, but they feel slightly different in use. The Mini Kelly’s structured Kelly shape gives it a classic, refined presence on the body, while the Constance 18’s sleek silhouette sits smoothly and discreetly. Both are comfortable, lightweight and easy to wear crossbody, making them practical grail bags despite their small capacities, as our crossbody guide explores.
The choice in wearability comes down to whether you prefer the structured Kelly presence or the sleek Constance profile, both of which wear beautifully as elegant small crossbody bags.
Value and demand
Both the Mini Kelly and Constance 18 command intense demand and strong resale value, sitting among the most coveted small bags in the market. The Mini Kelly, in particular, has achieved extraordinary desirability, often commanding significant premiums, while the Constance 18 enjoys strong, sustained demand. Both are excellent from a value perspective in classic specifications, so resale strength favours neither decisively, as our value retention guide notes.
Given their comparable desirability and value, the choice can rest on style and personal preference rather than resale considerations, as both are outstanding holders of value.
The H-clasp versus the Kelly closure
A defining aesthetic difference is the closure. The Constance 18 features the bold, iconic H-clasp as its central design element, a distinctive statement, while the Mini Kelly uses the classic Kelly turn-lock and strap closure, refined and traditional. This makes the Constance’s front more of a design focal point, while the Kelly’s elegance is in its overall structured silhouette. Your preference between the distinctive H-clasp and the classic Kelly closure often shapes the choice, as our Constance closure guide explores.
The final choice
Ultimately, the choice between the Mini Kelly and Constance 18 is a delightful one between two exquisite grail small bags, and neither is a wrong decision. It comes down to which iconic design you love more – the classic, structured Mini Kelly or the sleek, H-clasp Constance 18 – and both offer petite elegance, hands-free wearability and strong value. Choosing the design that speaks to your heart ensures a treasured small bag you will adore.
