I haven't experienced any of this at AMS ever. Policy is that a person may take about 2 pieces of fake clothing in total from those destinations(Malaysia/Thailand/Indonesia etc) without risking to get fined or that the goods will be destroyed. I travel quiet regularly from the SE region back to my home base AMS, so I think bringing two one or two shirts wouldn't be a big problem at all.

To give you another example I was flying back home over the holiday period(Christmas) with 2 bags filled with stuff, and was questioned by customs. When I told them I was back from a 2 month business/workshop trip in Singapore and Hong Kong they only scanned my bags and let me go. Whereas it was obvious that I had purchased goods there since it was either in a box or wrapping, which was visible on the scan, but I didn't need to either open my bags or show receipts.

Maybe it's because I am Dutch that they don't mind, but I don't get the impression they are any stricter for me than for foreigners. When it comes to all other countries in Europe I can't comment on this, but usually with 1 or 2 pieces of clothing they don't really mind from what I have experienced over at London and Frankfurt.
