Jack was a relieved guy.
He had been locked in these shoes and corset for 3 hours frantically searching the house for the key. The mistress whose advertisement he has answered had dressed him and made him up beautifully, but had then locked him in the clothes and threatened not to release him until he had spent 6 months as her slave. All he had to do now was unlock these things and he will be free ... although, he did like the hair and make-up, so he'll just slip a dress on and escape. But then again, he only had a frilly maids dress which he couldn't wear in the street ... and he didn't really want to take off these lovely stockings.
All things considered, Jack put the key back, slipped his maids dress back on and went about his duties.
