Are black and white patterned trousers allowed?

Dear Tanaya,  your clothes should be simple and light. No strip patters as they can be speculated to be able to hide communicative devices under datk colours. And pockets means you will be thoroughly checkes and you might feel inconvenient. So it is always best to keep it plain with no extrinsic designs, big buttons and embroidery. No ornamebts or jewellery of whatsover metal like chains, rings, anklets, nosepins, bangles, bracelets are allowed. Please team up your trouser with half sleeved kurti/kurta/top again which is simple, plain and light.
