Here are some ways to spot a fake Louis Vuitton purse:
They should have a Date code and Serial number NOT a model number: Real LV has 6 character date code or serial number. From left to right, char 1 and char 2 are letters where char 3 to char 6 are numbers.
If authentic, the char 3 is less than 1; the char 4 is higher than 8 with exception of 0; and, the char 5 and char 6 are numbers between 0 to 9. Vintage pieces may be vary from this rule; yet model number as code is big no no.
Every single multicolor item should have a date code that ends in the number 3 or 4 with no exceptions, Cherry Blossom for instance!
Stitching is perfectly hand stitched and proportionally aligned. Sloppy light color and uneven stitching is sign of a fake.
Authentic hand stitching looks like that every seam is at approx 45 degree (not 135 degree, when you see one you will know what I mean by). Machine stitching looks like many horizontal seam line up from head to toe.
Whole sale? Reputable major reseller? Used LV Suppliers? No such a thing. If wholesale LV bags are seen in listings or in an unverifiable private feedback listing, be very careful. Louis Vuitton doesn’t approve any individuals to be the whole sale representative!!
