Stick out like a sore thumb

This is not the Great Sphinx of Giza. As you know, the Great Sphinx of Giza is the largest one and its nose is missing. This is the Alabaster Sphinx of Memphis. When I went to Memphis, Egypt, the Sphinx lay in the museum without a roof; I mean right under the sizzling sun. By the way, before the trip I was wondering what I shall wear in Egypt at the beginning of October. People looked at me as a tourist, so I didn't have to dressed modestly all the time, but I sort of thought that at least covered shoulders and knees was a better idea, because when I was wearing a short-sleeved shirt and stuff, I stuck out like a sore thumb in Cairo and more.
