I don't like many of his designs, but hey, he's increased sales dramatically, and he's pulling customers in that may not have bothered with LV otherwise. He's giving the trend followers something to buy while also giving the regular customer base their famous classic styles that can be carried for eons. The company really does have something for most anyone.
If you like all leather, they've got it. If you want the famous Mono canvas, oh they've really got that one covered. If you want cherries, pandas, ostrich skin, graffiti-style branding, suede or perforated whatever, it's a done deal. Smart marketing IMO.
