Thames PM vs. Thames GM Comparison

Size & Capacity

The most important difference is, of course, size. The Thames PM is consciously compact - ideal for your wallet, smartphone, keys, sunglasses, and a lip gloss. Its tidy dimensions ensure it never feels overwhelming or gets in the way during a busy day.

In contrast, the Thames GM is built for capacity. At 13.4 inches long, it can comfortably accommodate everything the PM can hold, plus larger essentials like an iPad or a Kindle, a notebook, a planner, and even a makeup bag. This makes it a workhorse for the week and a perfect carryall for weekends.

Style & Aesthetic

While both bags share the same classic design, their size impacts their overall look and feel. The PM is sleek, subtle, and functions as more of an accessory. It complements an outfit without dominating it and is polished enough for dinner or a special event.

The GM has a much stronger presence. Its tote-like proportions make it more of a focal point. It projects a more practical, professional vibe well-suited for a work environment or as a sophisticated travel companion. Its larger surface area displays more of the iconic monogram or Damier canvas, making it a more noticeable statement piece.

Price & Value

The Thames PM is the more accessible option, typically costing around $2,000 to $2,200. It offers entry into Louis Vuitton's world of luxury craftsmanship without the bigger price tag of a larger bag. Its value lies in its versatile, everyday elegance.

Priced between $2,500 and $2,700, the GM requires a larger investment. However, if space is what you need, it arguably offers a better price-to-capacity ratio. For a few hundred dollars more, you get significantly more functionality and a bag that can serve multiple roles, from an office tote to an overnight bag.

Versatility & Daily Use

For daily errands, weekend brunch, or outings where you prioritize freedom of movement, the PM is the winner. It's light, sits securely on your shoulder, and keeps your essentials within easy reach. It's the bag you grab without a second thought.

The GM is the perfect M-F, 9-to-5 bag. It carries your work essentials with style and can easily transition to after-work plans. It’s also an excellent choice for parents who need extra room for snacks and essentials or for anyone who appreciates having all their necessities on hand just in case.

Which One Should You Choose?

Both models are excellent choices, but they cater to very different needs and priorities.

Choose the Thames PM if:

• You prefer carrying only the bare essentials.
• You want a lightweight, compact bag that isn't cumbersome.
• You are looking for a versatile luxury bag for daily errands, weekend plans, or casual evenings.
• You have a petite frame and find that larger bags feel overwhelming.

Choose the Thames GM if:

• You need a handbag that can hold bigger items like a tablet, planner, or notebook.
• You are looking for one bag that can serve multiple functions, from a daily work tote to a travel carry-on.
• You prefer a more substantial bag that makes a clear style statement.
• You value storage capacity and want the most room for your investment.

Can the Thames GM fit a laptop?

The Thames GM's 13.4" length may fit a very small notebook or an 11-inch tablet-style laptop, but it is not intended as a dedicated laptop bag. It's best suited for tablets, kindles, and A4-sized planners or notebooks. Always check your device's specific dimensions before purchasing.

Is the Louis Vuitton Thames line discontinued?

Yes, the Thames line has been discontinued by Louis Vuitton and is no longer available in boutiques. However, due to its classic design and durability, it remains very popular on the pre-owned market. You can often find them in excellent condition from reputable luxury resellers.

Which size is a better investment?

How do I care for the Vachetta leather trim?

The Thames PM is designed for your core essentials. It can comfortably hold a smartphone, a compact wallet, keys, a pair of sunglasses, and a few small makeup items like lipstick or a mirror.
