The shipping address must correspond the billing address of your credit card if you pay with CC or with PayPal address if you pay with PayPal. Otherwise LV can’t process your order. Also, you can’t order in USA website and ship to EU address, vice versa.
If I were you, just wait when you are in Germany/Netherlands.
Ask your partner to make a LV account on his name due to the shipping and billing regulations. I don’t know how long you are planning to stay, just remember if you want to buy these items via online platform then you have to stalk almost everyday (like other girls in this thread did).
Good luck!
