Renjuku, I wish you lots of luck for finding old school clothes. You'll need it.
Maybe you should check thrift and consignment shops in your area. You never know what you'll find there. Just use your imagination!
There's a huge list of VK brands
here, and I think it says whether the brand ships internationally or not.
If you find clothes that you really like from a brand that doesn't ship internationally, you can always use a shopping service such as
Celga.
Hope this helps. :]
