Continuity mistake: What top Dr. Casey Brackett is wearing (or not) in the decontamination chamber changes. Initially, she removes an off-white short-sleeved T-shirt-like top before putting on the protective gown. When she returns to the chamber, an automated voice says to "remove outer garment", which she does - but she is now wearing a sleeveless off-white top that was not under the gown. When she ducks down to hide from the Predator, she does not have ANY top on. (There may two+ different short-sleeved tops). (00:22:33 - 00:31:28)
