Our expert team of authenticators has another guide for you: Louis Vuitton Bumbag. Commonly known as the Louis Vuitton Fanny Pack.

Let’s see how to tell if your Louis Vuitton bag is real or fake.

How to spot a fake Louis Vuitton Bumbag

The best method to spot a fake Louis Vuitton Bumbag is to examine the engraving on the strap. Fakes often have inscriptions with incorrect thickness, and their stitching can be either too thick or too thin.

1. Strap

• Authentic:
  • Stitching: Thick, short threads on the strap.
  • “®” Symbol: Thicker and deeper embedded into the strap, with a centered and well-shaped “R”.
  • Text: Uniform thickness in both “LOUIS VUITTON” and “PARIS”.
• Fake:
  • Stitching: Thin, long threads on the strap.
  • “®” Symbol: Thin, with an “R” that has an overly long bottom right leg, making it off-center.
  • Text: Generally too thin, except for an anomalously thick “S” in “PARIS”.

2. Exterior tab

• Authentic:
  • Text: Thicker and more defined across all three lines on the tab.
• Fake:
  • Text: Noticeably thinner across all three lines on the tab.

3. Stitching

• Authentic:
  • Stitching: Straight and well-aligned at the top of the label.
  • Text: “LOUIS VUITTON” text is visibly thicker on the label.
• Fake:
  • Stitching: Noticeably thin and crooked, particularly at the top of the label.
  • Text: “LOUIS VUITTON” text on the label is too thin.

4. Interior label

• Authentic:
  • Text: Consistently the same thickness across all letters and lines, and slightly smaller in size.
  • Stitching: Uniform in thickness all around the square label.
• Fake:
  • Text: Exhibits variable thickness and is generally larger than on the authentic bag.
  • Stitching: Displays inconsistency in thickness, especially in the bottom right corner and right lateral side of the square label.

A quick mention:

• The steps we’ve written so far are the BEST ways to authenticate this item
• The next few steps are still reliable methods…
• … but they apply to non-top-versions of replicas available for this item

If in doubt, we recommend double-checking the steps we’ve explained above this line.

5. Date code

• Authentic:
  • Code Stamp: Has thicker, more defined letters and numbers.
  • Tab Color: Exhibits a darker shade, resembling real leather.
• Fake:
  • Code Stamp: Features thin letters and numbers.
  • Tab Color: Is notably lighter, providing a less authentic leather appearance.

6. Belt

Let’s look at the stitching on the interior side of the belt.

• Authentic:
  • Stitching: Appears thinner and less bulky, demonstrating precision and quality.
• Fake:
  • Stitching: Comes across as chunky and notably bulky, revealing inferior craftsmanship.

7. Buckle

• Authentic:
  • “LOUIS VUITTON” Text: Appears thinner and is not engraved as deeply into the metal, exhibiting a subtle and refined look.
• Fake:
  • “LOUIS VUITTON” Text: Appears too thick due to being engraved too deeply into the metal, providing a somewhat bulky appearance.

7. Zipper

• Authentic:
  • “LV” Text: Appears more subtle as it is not engraved deeply into the metal, presenting a refined appearance.
• Fake:
  • “LV” Text: Is engraved too deeply into the metal, resulting in a more pronounced and bulkier appearance.

9. Monogram

• Authentic:
  • Floral and “LV” Designs: Appear finer and thinner, maintaining a sophisticated and detailed appearance.
• Fake:
  • Floral and “LV” Designs: Exhibit a thicker presentation, which detracts from the refined look exhibited by genuine pieces.

10. Buckle frame

This is for the D-shaped buckle. The other part of it — the one that you close it.

• Authentic:
  • Metal Shine: Displays a subtler shine, reflecting light with less intensity.
• Fake:
  • Metal Shine: Noticeably shinier, exhibiting a higher reflectivity when exposed to light.

Shortlist: Check your Bumbag

These quick tips can help you spot a fake Louis Vuitton Bumbag:

1. Examine the strap; fake bags often have thin text and improperly shaped stitching.
2. Verify the inscription on the leather tab; replicas commonly have text at the wrong thickness.
3. Check the stitching at the top of the leather tab; fake bags may have stitching that’s too thick or too thin.
4. Inspect the interior square label; fake LV bags tend to have text and stitching at the wrong thickness.
5. Examine the date code’s tab inside the bag; fake Bumbags often have thin text and light-colored tabs.
6. Look at the stitching on the interior side of the belt; replica bags may have overly chunky stitching.
7. Examine the ‘LOUIS VUITTON’ text on the buckle; fake bags may have text that’s too thick.
8. Authenticate the ‘LV’ text engraved on the zipper; replicas may have text engraved too deeply into the metal.
9. Check the pattern around the bag; fake bags may have three types of flowers and thick ‘LV’ text.
10. Assess the shininess of the hardware details; fake LV bags may have overly shiny metal.
