Beige is 6 rivets, medium. Authentic products are between 2300 and 2700. It's an old model. It may not be sold in a physical store.
The green one I wore last time in Beijing is a new style this year, with a special price of 20 12 rivets. It is fluorescent green. Authentic around 3700.
I checked MCM official website. There are no physical stores in Shanxi, but there are two in Beijing, one is a specialty store and the other is a duty-free shop.
MCM Shop (M2010+M2011) on the second floor of Guangxin Tiandi, No.87 Jianguo Road, Chaoyang District, Beijing, with the postal code 100025.
