I purchased my first LouLou, medium sized - I ordered it online from FarFetch and when it arrived it was smaller than I was expecting. Upon measuring it I discovered it was only 30cm wide, whereas on the Saint Laurent website it says that the medium sized LouLou is 32cm wide. I started looking across different retailers and noticed that the exact size of the medium LouLou appears to vary depending on the colour/material, is this normal? I’m a little bit concerned I may not have an authentic bag…
