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