Tilda Swinton is Ready for Action

Tilda Swinton was at the Berlin red carpet thingy for her new movie "Hail Caeser" dressed in her best GI Joe clothes. I wonder... what if she wants to wear a wet-suit? Does she have to buy the whole Navy SEAL action pack (with grenades!) or can she just order the pants. Because what if you ruin a pair and have to order a new set? What do you do with all those extra spear guns and SCUBA tanks?
