You might be here because you:

  • Have a YSL LouLou bag
  • Are not sure if it’s original or not
  • So you want to learn how to verify it

This is the place to be in. We’ve set up the ultimate YSL LouLou authentication guide.

Per our expert YSL authenticators, this guide highlights the top 7 spots to check for verifying your bag.

Let’s check it out!

How you can tell if a YSL LouLou is fake

Start with the inner ‘SAINT LAURENT PARIS’ interior label. Replicas often falter in font-weight here.

Discover our top seven clues to spot these counterfeits effortlessly.

1. Interior label

  • Authentic: “SAINT LAURENT PARIS” print is thick.
  • Fake: “SAINT LAURENT PARIS” print is thin and noticeably different from the authentic bag.

2. YSL metal logo

  • Authentic:
    1. Gaps in metal areas where “Y” meets “S” are shallower.
    2. Corners of the letter “S” are sharper.
    3. The vertical leg of “L” is thicker.
  • Fake:
    1. Gaps in metal areas where “Y” meets “S” are deeper.
    2. Corners of the letter “S” are less sharp.
    3. The vertical leg of “L” is thinner.

3. SLP printed logo

  • Authentic: Side printing is thicker and larger.
  • Fake: Side printing is thinner and smaller.

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.

4. Shape

  • Authentic: Deeper indentation.
  • Fake: Shallower indentation.

5. Back

  • Authentic: Deeper stitches, more defined.
  • Fake: Shallower stitches, less defined.

6. Bottom

  • Authentic: Genuine leather bottom material.
  • Fake: Fake leather material with a more textured appearance.

7. Carbine

  • Authentic: “SAINT LAURENT” text on the carbines is printed less deeply.
  • Fake: “SAINT LAURENT” text on the carbines is printed more deeply.

Shortlist: Verify your YSL LouLou

  1. Inner Text Examination: Ensure the “YVES SAINT LAURENT PARIS” print isn’t too thin.
  2. Front “YSL” Logo Analysis: Genuine logos are not overly thin or curvy; watch for too-deep spaces where the letters merge.
  3. Side “SAINT LAURENT” Printing: Authentic bags don’t have text that’s overly small or thin.
  4. Side Dent Inspection: Authentic YSL bags feature a more pronounced dent.
  5. Rear Pattern Stitching: Check that the stitching isn’t shallow; it should be adequately deep.
  6. Bottom Material Check: Genuine YSL Loulou bags utilize real leather at the base.
  7. Carbine “SAINT LAURENT” Print: Counterfeit bags often have overly deep text impressions on the carbines.

Above are the top 7 signs to quickly discern between an real vs fake Yves Saint Laurent Loulou.
