You can hide small MP3 players and stuff into headphones , worked for me
Getting new armani clothes is a lil harder , my plan was simple , stuff + remote control car , the store where i went had a large space above ceiling and ceiling panels , i putted clothes up there and a remote control car , clothes onto it , and controlled it over ceiling to toilet ceiling , went to toilet took clothes and other stuff i took packed to backpack ( i had some foodstuff there already , 2 pizzas and 2litre cola ), and walked out with new stuff ^^,
(I had a fairly big backpack , in the end it had 2 armani shirts , 1 pair of pants , 2 armani perfumes , 1 iPhones ,)
security was like "Hey put that stuff back where u took it , but
) , i didnt had it in my backpack when i left main store part)
