The BB is a compact, chic bag designed to carry just the essentials with dimensions of 8.3" x 6.7", while the much larger MM (13.4" x 9.4") serves as a spacious daily work or travel companion, easily holding a small tablet and more.

Louis Vuitton Montaigne BB vs. MM Comparison

Size & Capacity

The most significant difference is the sheer size. The Montaigne BB is truly a mini bag, perfect for your smartphone, a card case, keys, and a few small makeup items. It forces you to be selective about what you carry and is ideal for users who travel light.

In contrast, the Montaigne MM offers substantial space. You can comfortably fit a standard iPad, a notebook, a full-size wallet, a makeup bag, sunglasses in a case, and even a small water bottle. Its central zippered compartment is great for securing valuable items, making it far more suited for a 9-to-5 workday or as a carry-on personal item.

Style & Versatility

While both bags are undeniably chic, their size influences their overall feel and best use cases. The BB’s small scale lends itself to greater versatility in styling. It looks just as appropriate with an evening dress as it does with jeans and a blazer for brunch. The crossbody strap makes it a fantastic, hands-free option for shopping or weekend activities.

The MM has a more formal, commanding presence. Its primary role is that of a sophisticated day bag or work tote. While it can certainly be used on weekends, its size and structure make it less suited for casual, on-the-go moments and better for situations where you need to carry more and look polished doing it.

How They Carry

How you prefer to carry your bag is a critical deciding factor. The Montaigne BB is lightweight and effortless. It's delightful to carry by its dainty top handles, but the real star is the removable strap that allows for comfortable shoulder and crossbody wear, keeping your hands free.

The Montaigne MM is a stark contrast. It's a heavier bag, even when empty, and is primarily designed to be carried by its sturdy top handles or on the shoulder. While it comes with a strap, its size makes wearing it crossbody awkward and bulky for most people. It's more of a handheld or shoulder-carry bag.

Price & Value

The price difference between the two models is significant, often around $700 or more. The Montaigne MM's higher price is justified by its larger size, increased material usage, and greater functionality as a work bag. If you need a daily carryall, the MM provides better value through its practicality.

The Montaigne BB offers value for those seeking the iconic LV style in a smaller, more event-ready package. It serves a different purpose, acting as a luxury accessory rather than a utility bag. Your decision should be based on which style provides more value for your specific lifestyle and needs.

Which One Should You Choose?

Both the Montaigne BB and MM are beautiful, functional bags, but they cater to very different needs.

Choose the Montaigne BB if:

• You only carry essentials like your phone, keys, and a cardholder.
• You want a lightweight bag that offers a hands-free crossbody option.
• You need a versatile bag that transitions seamlessly from day to evening.
• Your style is classic and minimalist, and you prefer understated accessories.

Choose the Montaigne MM if:

• You need a primary work bag that can hold a tablet, notebook, and other daily items.
• You prioritize capacity and organization over a compact size.
• You prefer carrying your bag by the top handles or on your shoulder.
• You want a sophisticated, structured bag with a strong presence for professional settings.
