Clothing - Fashion / Modest Clothing Import and Export Activities in Poland

To whom it may concern, I am interested in importing to Poland T-shirts, tunics and trousers. Please tell me how much will cost 10/50/100 ps. Do you have sample catalog? I plan to export clothed to Poland so please let me know if you have all necessary documents to get A.TR. at the border? Best regards Ewa Schumacher
