Marina testified that she thinks that was the shirt he wore that morning.
"thinks"?....
Mr. RANKIN. Mrs. Oswald, would you step over with the interpreter to this desk and point out the different pieces of clothing as we ask you about it, please?
Do you know the shirt that Lee Oswald wore the morning that he left?
Mrs. OSWALD. I don't remember. What else interests you? What do you want?
Marina did not see him leave the house and had no way of knowing which shirt Oswald was wearing.
Bledsoe testified it was the same shirt.
Bledsoe's testimony was all over the place. She was shown the actual shirt at her home before testifying and only "recognized" it due to the hole on the arm. 
None of the people who worked with Oswald that morningwere able to identify that shirt! And it is common knowledge that eyewitnesses frequently get all sorts of details wrong, yet Bledsoe's convenient testimony is believed without question or corroboration.
A good-sized hole in a sleeve would be arguably more noticeable, and recalled, than the actual shirt itself
Seems Oswald wasn't very noticeable most of that day
The poor drab sap in a drab shirt. Could barely get even what he was carrying noticed
Seems no one hardly noticed him his entire life
They notice him now, huh...
