What's wrong with this outfit?

Is it the shoes? the tights? the undershirt? Can I leave my house looking like this?

Another Jewish Holiday, another post revolving around socks!

My husband thinks this is a totally inappropriate use of sock wearing. He thinks I should be embarassed to leave the house like this, let alone travel to another country. This is my "travel outfit" I don't like going barefoot to the airport because you have to take your shoes off to go through security.

















Is this passable or should I rethink my travel outfit?
