I agree that if Caylee's clothing was removed, Casey likely hid the clothing so that it would be found. The alleged "they haven't even found her clothes" statement seemed, IMO, to reveal the order Casey anticipated the recovery effort to follow. Perhaps she was amused that LE and searchers were just chasing their tails in her little mousetrap game. Perhaps she was also annoyed that the clothes hadn't been found sooner-- more and more time elapsed and still no evidence could substantiate Casey's abduction story, making Casey look guiltier with each passing day. The Universal idea makes a lot of sense because Casey took LE there to ask security if they had "seen Caylee." Perhaps she thought the clothing would have been discovered by then, security would hand it over to LE, and that evidence would naturally frame Caylee's disappearance as a believable abduction from "Day One."
In the interview with LE, Casey provided a strange and, IMO, revealing response when asked whether Caylee had a birthmark or other identifying features: "Caylee has very distinctive features, even if her hair was cut or changed
LE didn't say anything about Caylee's hair being cut or changed. Casey just blurted that out. I think Casey used the cliche mall abduction scenario as her template-- an abductor grabs a child, takes them into the bathroom and cuts their hair and changes their clothes-- abductors abscond with little girls by making them look like little boys, etc. I think she could have planted Caylee's clothing in a relatively conspicuous location, believing its recovery would substantiate the kidnapping scenario. If Caylee's body was found unclothed, I get a really creepy feeling that we could also find out that her hair was "cut or changed."
